WEBVTT 00:01.670 --> 00:07.100 Prof: Okay, we are now at the part of the 00:07.095 --> 00:10.635 course-- we're coming up to fairly 00:10.637 --> 00:14.347 modern times, it's been a very breathless run 00:14.350 --> 00:18.250 from six million years of chimpanzee evolution through 00:18.248 --> 00:20.778 many-- few million years of human 00:20.777 --> 00:24.277 evolution, and we're coming up to more or 00:24.282 --> 00:28.392 less the 1960s, which is the period of the 00:28.388 --> 00:34.808 greatest percentage increase in human population on earth ever. 00:34.810 --> 00:39.220 So this is the peak of what's called the population explosion 00:39.215 --> 00:43.615 and we're going to be talking about that until almost the end 00:43.621 --> 00:45.091 of the term now. 00:45.090 --> 00:52.740 I have to tell you a little bit, truth in teaching or 00:52.743 --> 00:54.513 something. 00:54.510 --> 00:59.540 How I got interested in this topic. 00:59.540 --> 01:02.290 When I was just a little bit older then you are now, 01:02.289 --> 01:07.209 I did the fairly usual thing of going-- 01:07.209 --> 01:10.299 putting on my short pants and going around the world, 01:10.299 --> 01:15.009 around Asia anyway, with almost no money in my 01:15.007 --> 01:15.947 pocket. 01:15.950 --> 01:18.810 You all, if you have never done that, you should do it 01:18.805 --> 01:21.875 definitely, and after you graduate college is a great time 01:21.879 --> 01:22.579 to do it. 01:22.580 --> 01:25.730 One of the places I went to was Hong Kong. 01:25.730 --> 01:28.930 Now Hong Kong at that time there were huge numbers of 01:28.933 --> 01:30.723 people coming out of China. 01:30.720 --> 01:34.050 China was still extraordinarily poor at the time, 01:34.050 --> 01:36.710 and any time anybody could leave they left, 01:36.709 --> 01:41.069 and so Hong Kong was incredibly crowded with very poor people 01:41.069 --> 01:45.139 and it's still an incredibly crowded place of course, 01:45.140 --> 01:49.190 and migrants are still coming out if they can. 01:49.190 --> 01:53.760 One of the--where were these people going to live? 01:53.760 --> 01:56.060 There were hillsides with shanty towns, 01:56.060 --> 01:59.190 lots and lots of shanty towns, but also the-- 01:59.190 --> 02:02.170 it's right on the ocean, it's an island, 02:02.170 --> 02:05.240 part of it's an island, so the water is free so many 02:05.241 --> 02:07.651 people were living in little sampans, 02:07.650 --> 02:13.250 little boats called sampans in--just in the harbor docked 02:13.250 --> 02:15.850 sort of almost anywhere. 02:15.848 --> 02:19.068 I thought well that's interesting, and one of my 02:19.066 --> 02:22.966 friends, I had a number of Chinese friends took me to look 02:22.966 --> 02:24.126 at the boats. 02:24.128 --> 02:27.808 It was interesting, I wasn't yet really interested 02:27.806 --> 02:32.306 in demography but I couldn't help notice that basically every 02:32.311 --> 02:36.141 boat had a little girl on it 11,12, 13 or something, 02:36.138 --> 02:37.638 maybe younger. 02:37.639 --> 02:40.909 And then we got invited on the boat, 02:40.910 --> 02:44.770 one of the first--one of the boats and people were extremely 02:44.774 --> 02:46.744 polite, even the very poor, 02:46.739 --> 02:51.079 very polite and a lot of bowing and shaking hands on my part, 02:51.080 --> 02:52.930 and they wanted to offer me something, 02:52.930 --> 02:55.400 a little bit of tea, a little bit of rice cake, 02:55.400 --> 02:58.540 they're just as wonderful as they could be. 02:58.538 --> 03:01.268 I noticed that when something had to be done like the tea had 03:01.270 --> 03:03.440 to be gotten, or this that or the other 03:03.443 --> 03:06.913 thing, it was that little girl that was doing all the work. 03:06.908 --> 03:09.558 Okay, so what, that's one the kids, 03:09.562 --> 03:12.762 it's good for kids to have some chores. 03:12.758 --> 03:15.698 Then since--they didn't have didn't have television or a lot 03:15.699 --> 03:18.689 of entertainment and here was this Westerner and they weren't 03:18.688 --> 03:21.578 so used to seeing a lot of Westerners on their boats-- 03:21.580 --> 03:23.670 I sort of got passed from boat to boat. 03:23.669 --> 03:25.279 When you go walking around the world that's a very good, 03:25.280 --> 03:28.530 if you go to places where they don't see Westerners you can get 03:28.528 --> 03:32.068 passed on very easily-- so in boat after boat--and this 03:32.072 --> 03:35.982 phenomenon repeated itself, that there was this little girl 03:35.979 --> 03:39.209 in every boat and she seemed to be doing all the work. 03:39.210 --> 03:44.040 Finally, I asked my friends, what's going on here? 03:44.038 --> 03:47.588 A little hard to get the information out of them, 03:47.590 --> 03:52.950 but in actual fact it was a form of shall we say family 03:52.950 --> 03:57.290 population control that the-- there--this was a 03:57.291 --> 04:01.741 non-contracepting population so children just coming and they 04:01.743 --> 04:06.273 couldn't support the number of children that they had and they 04:06.271 --> 04:08.871 did not value girls very much. 04:08.870 --> 04:12.650 What they did is, basically, they sold the girls 04:12.646 --> 04:17.206 from one boat to the next boat, and then the little girls were 04:17.209 --> 04:19.519 basically servants, again you can use the word 04:19.524 --> 04:23.014 slave it you want, but servants in whatever boat 04:23.005 --> 04:27.245 they had been sold to, and some money changed hands, 04:27.250 --> 04:31.500 of course all illegal because Hong Kong was then under British 04:31.502 --> 04:32.132 rules. 04:32.129 --> 04:35.639 It's illegal almost everywhere anyway. 04:35.639 --> 04:40.069 They were just working, doing as much work as could be 04:40.065 --> 04:41.815 gotten out of them. 04:41.819 --> 04:44.919 Well that was very sad, but it wasn't a disaster 04:44.916 --> 04:47.746 because everybody was living very poorly. 04:47.750 --> 04:52.780 Then later, same trip, with my medical connections, 04:52.779 --> 04:55.869 I got to tour one of the big British-- 04:55.870 --> 04:58.760 Queen Elizabeth Hospital, one of these big city 04:58.762 --> 05:01.102 hospitals, it had ward after ward, 05:01.095 --> 05:03.925 and one of the things I was taken to see-- 05:03.930 --> 05:06.890 tuberculosis was a very big problem back then, 05:06.889 --> 05:10.379 leprosy was a problem, tuberculosis was a problem. 05:10.379 --> 05:12.119 I did something stupid with leprosy I visited-- 05:12.120 --> 05:16.460 there was a leper colony on an island off of Hong Kong and they 05:16.459 --> 05:20.249 were constructing stuff, and I cannot stand around while 05:20.245 --> 05:23.485 people are working and me not so I grabbed a pitch-- 05:23.490 --> 05:29.330 a pickax and started working with them and of course the 05:29.329 --> 05:31.239 pickax is rough. 05:31.240 --> 05:34.680 It's made of not terribly well polished wood and there I was 05:34.677 --> 05:37.297 banging away with it and it rubs whatever-- 05:37.300 --> 05:41.340 Leprosy is a bacteria that gets into your skin and the only way 05:41.343 --> 05:44.673 to get it is to get that leprosy into your skin, 05:44.670 --> 05:48.140 so the lepers had been working with it and rubbing it into 05:48.137 --> 05:52.027 their skin and they were rubbing into the wood of the ax and then 05:52.029 --> 05:52.759 onto me. 05:52.759 --> 05:57.249 I did not get--it was really stupid in retrospect but you do 05:57.254 --> 06:01.374 a lot of stupid things and I did not catch leprosy, 06:01.370 --> 06:05.240 and in fact, by that time most--they had a 06:05.244 --> 06:07.964 drug, an antibiotic against leprosy 06:07.963 --> 06:12.033 and most of the leprosy bacillus in these people was dead, 06:12.028 --> 06:15.548 so it probably wasn't quite as dangerous as it might have been. 06:15.550 --> 06:20.720 Anyway, I did not catch leprosy; you can check my hand and so 06:20.723 --> 06:21.393 forth. 06:21.389 --> 06:24.679 The people there had the old--this is an aside but it's 06:24.678 --> 06:26.688 about poverty so I'll tell you. 06:26.689 --> 06:30.399 Leprosy affects the nerve cells and it doesn't make-- 06:30.399 --> 06:32.859 directly make your fingers or nose fall off, 06:32.860 --> 06:36.010 but you don't feel wounds, so you don't-- 06:36.009 --> 06:36.909 because you don't have the nerve cells-- 06:36.910 --> 06:41.850 so you don't take care of wounds, eventually the fingers 06:41.853 --> 06:45.983 get infected and damaged, the damage is kind of constant 06:45.978 --> 06:47.908 and parts of you fall off actually. 06:47.910 --> 06:49.750 But it's not the leprosy bacteria itself, 06:49.750 --> 06:52.460 which only attacks nerves, it's the damage that you're not 06:52.463 --> 06:54.483 paying-- you're not noticing, 06:54.480 --> 06:56.100 you're not aware of. 06:56.100 --> 06:58.430 Sorry that was an excursion. 06:58.430 --> 07:01.040 Leprosy was a big thing in Hong Kong at that time, 07:01.040 --> 07:05.400 as was tuberculosis and in the big British hospital I went in 07:05.403 --> 07:08.753 and one of the things I saw was huge wards, 07:08.750 --> 07:14.190 they're big places with--again I saw a ward full of these just 07:14.187 --> 07:19.087 pubescent or pre-pubescent girls and they all had TB. 07:19.089 --> 07:22.379 Then there was two or three of these wards actually, 07:22.380 --> 07:26.320 so a very large number of girls there, and I said what's going 07:26.317 --> 07:26.767 on? 07:26.769 --> 07:29.639 Then the full story came out. 07:29.639 --> 07:32.869 That yes, indeed, there is a lot of selling of 07:32.874 --> 07:36.274 the children between boats, and yes they work, 07:36.269 --> 07:39.849 and because they're underfed and overworked and TB is 07:39.853 --> 07:44.213 rampant, these girls get tuberculosis. 07:44.209 --> 07:48.249 Then what happens is they take them to the health station and 07:48.249 --> 07:52.359 the doctors say you've got to build up this girl and they give 07:52.355 --> 07:53.765 them milk powder. 07:53.769 --> 07:58.159 Milk powder is taken, and what do you think they do 07:58.160 --> 08:00.180 with the milk powder? 08:00.180 --> 08:03.880 Give it to the boy child, so the girl gets sicker, 08:03.879 --> 08:06.859 and then she's getting quite sick and she's brought back, 08:06.860 --> 08:10.170 and now she's given medicine, an antibiotic, 08:10.170 --> 08:11.980 and guess what happens with medicine? 08:11.980 --> 08:16.640 Taken to the market, sold, the money is used to buy 08:16.636 --> 08:19.986 rice or milk for the boy children. 08:19.990 --> 08:22.800 Eventually--so TB, as you're probably aware, 08:22.800 --> 08:25.750 gets the lungs, it can also get in the long 08:25.752 --> 08:28.592 bones of the body, and eventually it infects the 08:28.593 --> 08:30.383 long bones and the long bones start-- 08:30.379 --> 08:33.359 huge amounts of pus builds up and eventually it breaks through 08:33.363 --> 08:37.023 the skin, so someone who has a child with 08:37.020 --> 08:42.670 this kind of long bone tuberculosis sees basically pus, 08:42.668 --> 08:45.658 the skin eventually breaks and the pus starts pouring out, 08:45.658 --> 08:49.638 and the parents are terribly afraid and they're afraid for 08:49.643 --> 08:52.733 their biological kids, their biological sons 08:52.731 --> 08:53.501 especially. 08:53.500 --> 08:59.520 As soon as this happens to the girl they just dump her at the 08:59.520 --> 09:05.140 British--at whatever the public hospital is and they just 09:05.140 --> 09:07.450 abandon them there. 09:07.450 --> 09:12.360 What the doctors told me was that the girls are now 13 or 14, 09:12.357 --> 09:17.267 the tuberculosis is so far gone that there's nothing they can 09:17.267 --> 09:17.837 do. 09:17.840 --> 09:20.790 And the girls die. 09:20.788 --> 09:25.908 This was my first introduction to that nexus of extreme 09:25.914 --> 09:29.774 poverty, extremely crowded conditions, 09:29.770 --> 09:33.150 overpopulation, and I'm not saying the causal 09:33.154 --> 09:36.804 relationship between those two is a complicated story which we 09:36.803 --> 09:39.473 will get to, but that nexus of--you always 09:39.466 --> 09:43.236 see, whenever you see incredibly dense populations you always see 09:43.235 --> 09:46.465 this kind of poverty and the kinds of things that people 09:46.474 --> 09:47.244 undergo. 09:47.240 --> 09:50.440 I was trying to put myself in the mind of a parent, 09:50.440 --> 09:54.410 what kind of a situation are they are in, 09:54.408 --> 09:58.998 that they sell their daughters to fairly certain death and the 09:59.000 --> 10:02.010 situation is as I've described to you. 10:02.009 --> 10:07.179 Even though I saw this as a huge--as a very large phenomenon 10:07.183 --> 10:10.783 I've never seen this in any literature. 10:10.778 --> 10:12.418 I've never seen an academic paper about it, 10:12.418 --> 10:15.968 I've never seen a newspaper story about it, 10:15.970 --> 10:18.490 it's not discussed in demographic circles, 10:18.490 --> 10:21.180 and some public health circles which I'm aware, 10:21.179 --> 10:24.769 it just isn't brought up. 10:24.769 --> 10:27.599 I'm thinking to myself, I was not a scholar of this 10:27.604 --> 10:30.104 thing, and I said, "have I misremembered 10:30.099 --> 10:30.949 this?" 10:30.950 --> 10:33.770 You very frequently misremember things, have I blown up, 10:33.774 --> 10:37.014 did I see one or two cases and have I somehow aggrandized it. 10:37.009 --> 10:39.049 I eventually, after telling the story quite a 10:39.046 --> 10:41.676 bit, even in the early runnings of 10:41.676 --> 10:44.586 this class, I started doubting that 10:44.586 --> 10:47.386 this--that somehow-- why such a big thing, 10:47.394 --> 10:48.494 why wasn't it shown? 10:48.490 --> 10:50.330 One year I decided: this is the last year; 10:50.330 --> 10:52.950 I'm not going to tell this story again because I don't have 10:52.947 --> 10:54.027 any references for it. 10:54.029 --> 10:57.229 Everything I say I try to--if a student comes to me I can give 10:57.227 --> 11:00.317 you a reference and you can see in the notes a lot of things 11:00.322 --> 11:03.572 have little references which you probably can't read but if you 11:03.573 --> 11:06.623 call me or email me I'll tell you what that little scribble 11:06.615 --> 11:07.345 means. 11:07.350 --> 11:11.470 Anyway at the end of that lecture, actually it was about 11:11.470 --> 11:14.770 two lectures later, because there was an exam 11:14.767 --> 11:17.087 coming up right after that. 11:17.090 --> 11:20.140 More than in this class, in previous years, 11:20.139 --> 11:23.289 students used to come up and we used to spend a half an hour or 11:23.288 --> 11:25.878 an hour discussing whatever they want to discuss. 11:25.879 --> 11:29.289 And one girl stayed by the side and then when everybody is gone 11:29.293 --> 11:31.823 she came up to me, a little bit shy, 11:31.820 --> 11:35.850 and said, "Thank you for telling that story. 11:35.850 --> 11:38.630 My mother was one of those girls." 11:38.629 --> 11:41.099 What she knew, from her mother, 11:41.096 --> 11:46.196 was basically what I had said, but the difference was that 11:46.198 --> 11:50.978 this was her biological mother, and this wasn't an abandoned 11:50.980 --> 11:51.380 girl. 11:51.379 --> 11:54.189 She said she remembered being in the hospital with all girls 11:54.190 --> 11:59.280 basically-- the mother--I said "Oh my 11:59.277 --> 12:02.397 gosh, would your mother come to class 12:02.403 --> 12:05.703 and describe what this situation was like?" 12:05.700 --> 12:09.460 Yes, the mother was in fact a professor at a college in New 12:09.461 --> 12:11.101 Jersey, not Princeton, 12:11.096 --> 12:13.916 and she came up here and described it, 12:13.918 --> 12:18.718 and again, described it in great detail and more or less as 12:18.716 --> 12:20.366 I've described it. 12:20.370 --> 12:23.140 She said that when she was in the hospital, 12:23.139 --> 12:24.379 she saw all the other little girls, 12:24.379 --> 12:27.149 more or less the same age, same medical problem, 12:27.149 --> 12:28.839 and she said, as a little girl she always 12:28.841 --> 12:31.101 wondered why their parent-- their mother didn't come to 12:31.101 --> 12:32.691 visit them, why their parents didn't come 12:32.687 --> 12:33.247 to visit them. 12:33.250 --> 12:36.680 She was one of the few whose mother--I guess the father, 12:36.682 --> 12:40.242 I don't really remember that detail, did come to visit. 12:40.240 --> 12:44.780 Well the doctors kind of noticed that this girl had a 12:44.784 --> 12:50.034 bio-parent and so they took her out of the big ward and put a 12:50.029 --> 12:54.749 lot of incredibly special effort into this one girl and 12:54.750 --> 13:00.170 eventually she got the bacteria out of her and survived. 13:00.168 --> 13:06.198 She was--walked like this, missing a hip and had a fair 13:06.201 --> 13:10.561 number of sequelae from the bone TB, 13:10.558 --> 13:13.828 but she got cured, grew up, managed to get 13:13.831 --> 13:16.071 educated, migrate to America, 13:16.067 --> 13:19.847 and became a professor at, as I say at a college in New 13:19.851 --> 13:23.521 Jersey and had a daughter at Yale taking this course. 13:23.519 --> 13:30.969 It's one of the miracle stories but I'm convinced now that I 13:30.967 --> 13:34.627 didn't dream this stuff up. 13:34.629 --> 13:38.399 That's really my personal motivation, that started of 13:38.404 --> 13:42.254 course the motivation for being--doing all this course 13:42.253 --> 13:42.983 stuff. 13:42.980 --> 13:51.100 What's the word we describe for this era of the 1960s? 13:51.100 --> 13:54.870 The population explosion. 13:54.870 --> 13:57.020 Why do we use the word explosion? 13:57.019 --> 14:01.899 It's a rather emotive kind of word and it's for this reason, 14:01.899 --> 14:06.789 that here is a somewhat fanciful recreation of history, 14:06.788 --> 14:09.508 but we know it can't be very much different from this because 14:09.511 --> 14:11.621 we know what the-- we start knowing what the 14:11.618 --> 14:14.178 populations were here, so you put some sort of a 14:14.182 --> 14:16.502 reasonable growth rate and populations, 14:16.500 --> 14:18.390 its going to look like that. 14:18.389 --> 14:21.299 The only thing you can really see is the Black Death, 14:21.298 --> 14:23.928 then as we've talked about in this class, 14:23.928 --> 14:30.338 starting roughly in the 1700s population just takes off. 14:30.340 --> 14:34.130 You've heard of exponential population growth, 14:34.129 --> 14:36.759 and you may or may not know what that means, 14:36.759 --> 14:39.849 but what it precisely means is there's a certain rate of 14:39.847 --> 14:42.167 growth, a certain percent per year, 14:42.166 --> 14:45.936 and each year the population grows by that same percent, 14:45.940 --> 14:50.140 1% a year, 2% a year, 3% a year, but the percentage 14:50.144 --> 14:51.914 growth is constant. 14:51.908 --> 14:55.378 The numbers of people added every year grows because the 14:55.384 --> 14:59.114 base grows, but the percentage added every year is constant, 14:59.114 --> 15:01.014 that's exponential growth. 15:01.009 --> 15:04.739 In fact, during this period, in fact during most of this 15:04.740 --> 15:08.810 period, the percentage rate of growth has been increasing. 15:08.808 --> 15:16.948 It increased from somewhere out here of .001% to then 0.01,0.1 15:16.952 --> 15:22.162 and in this period it went up to 2%, 15:22.158 --> 15:26.548 even 3% globally, the whole world population 15:26.553 --> 15:30.953 growth rate in this incredible expansion. 15:30.950 --> 15:34.110 As you can sort of see again, in this somewhat schematized 15:34.110 --> 15:36.650 graph, that the incredible rate of 15:36.653 --> 15:41.193 growth has slowed down a little bit and we'll talk about what 15:41.193 --> 15:43.773 that means, but it's still growing 15:43.774 --> 15:46.924 outrageously, or they project that it should 15:46.918 --> 15:47.708 slow down. 15:47.710 --> 15:54.370 This is--we are now at about 6.7 billion so some of that 15:54.365 --> 15:57.265 graph is a projection. 15:57.269 --> 16:00.319 You can call this kind of population growth 16:00.317 --> 16:02.927 hyper-exponential where the rate, 16:02.928 --> 16:07.888 not only does the growth get faster in an exponential way, 16:07.889 --> 16:12.339 but the rate of growth itself grows so it's hyper-exponential 16:12.341 --> 16:13.011 growth. 16:13.009 --> 16:17.659 Now there's a--the whole issue of population growth is very 16:17.657 --> 16:21.707 politicized, some people don't think that we 16:21.712 --> 16:23.782 should pay-- there's no problems, 16:23.777 --> 16:26.117 some people think we shouldn't do anything about it, 16:26.120 --> 16:30.270 some people think it's too politically sensitive to say 16:30.274 --> 16:33.914 anything about it, and in this discussion one of 16:33.908 --> 16:37.388 the things you hear is, oh the world's population has 16:37.394 --> 16:41.324 been growing for a long time, we've been able to cope with 16:41.320 --> 16:45.410 it, our economics is wonderful, and we've industrialized, 16:45.410 --> 16:47.670 the population has been growing, 16:47.668 --> 16:50.378 and people have been getting richer and that is certainly 16:50.383 --> 16:53.613 true since Malthus wrote, the population has multiplied 16:53.607 --> 16:57.337 many times and yet these mass, mass starvations have not 16:57.341 --> 16:58.011 happened. 16:58.009 --> 17:00.539 In fact, not only, as the population has grown, 17:00.538 --> 17:02.078 people have gotten richer. 17:02.080 --> 17:05.900 They say, we've coped with this in the past we can cope with it 17:05.903 --> 17:06.893 in the future. 17:06.890 --> 17:10.030 The problem is that this is unprecedented. 17:10.028 --> 17:13.388 That we don't really have any significant length of history 17:13.386 --> 17:16.166 for something like this, so anybody who tells you that 17:16.173 --> 17:18.793 they have-- that they know what's going to 17:18.789 --> 17:22.939 happen in the future is just ignorant and this is absolutely 17:22.939 --> 17:25.049 and just unknown territory. 17:25.048 --> 17:27.218 Unknown territory doesn't mean, I'm not saying there's 17:27.217 --> 17:28.727 absolutely going to be a disaster, 17:28.730 --> 17:30.810 or it's absolutely going to be fine, 17:30.808 --> 17:34.528 it's just that we have no way of predicting basically anything 17:34.525 --> 17:36.835 with a population growing like that. 17:36.838 --> 17:39.848 Up until a few years ago basically nobody predicted all 17:39.848 --> 17:42.678 the environmental-- for instance nobody predicted 17:42.680 --> 17:45.830 all the environmental problems that we're having now, 17:45.828 --> 17:49.938 that came essentially out of the blue. 17:49.940 --> 17:55.460 Now this is a schematized thing, here's kind of a more 17:55.461 --> 17:58.071 cartoonish, even more cartoonish, 17:58.068 --> 18:01.458 but it doesn't go quite so far back so it's a little bit better 18:01.462 --> 18:03.752 data here, and again, showing the same 18:03.753 --> 18:04.153 thing. 18:04.150 --> 18:07.230 This was--you're here this was drawn in 2004, 18:07.230 --> 18:12.120 we're now in 2008 and we're about 6.7 so in just the four 18:12.123 --> 18:17.283 years since this was made we're still on this trajectory; 18:17.278 --> 18:22.128 nothing very unexpected has happened. 18:22.130 --> 18:26.010 Here is the U.S. Census Bureau projection, 18:26.011 --> 18:30.751 updated December 2008, so it's as recent as you can 18:30.748 --> 18:31.788 find. 18:31.788 --> 18:35.708 For what's happened--they do 100 years and you may notice 18:35.710 --> 18:37.600 three billion, four billion, 18:37.598 --> 18:39.628 five, six, seven, eight, nine, 18:39.630 --> 18:43.970 and it just keeps going and out at the end they're predicting a 18:43.970 --> 18:47.610 little bit of fall off but one doesn't know. 18:47.608 --> 18:54.338 By 2040 they're expecting nine billion people and still 18:54.343 --> 18:55.593 growing. 18:55.588 --> 19:00.438 There's no--you've heard a lot about Europe and Michael 19:00.436 --> 19:06.086 Teitelbaum gave you a lecture on the low population growth rates 19:06.093 --> 19:09.643 in Europe, in Japan, and in quite a number 19:09.635 --> 19:13.315 of countries in the world and that's correct that the 19:13.319 --> 19:17.429 population growth is extremely unbalanced in the world. 19:17.430 --> 19:22.260 The developed countries are having zero to at most 5% of the 19:22.258 --> 19:24.788 increase, they're growing at .1%, 19:24.792 --> 19:28.642 whereas, some of the poorer countries are still growing at 19:28.642 --> 19:31.062 2% or 3%, so I'll show you a minute that 19:31.060 --> 19:34.140 basically all of this growth is in the poorer countries where 19:34.144 --> 19:37.524 they're least-- have the least resources to 19:37.518 --> 19:40.508 cope with this amount of growth. 19:40.509 --> 19:46.459 Now here is the population change in millions and we'll see 19:46.459 --> 19:50.459 that that has basically been growing. 19:50.460 --> 19:57.300 This is where we are now, it basically grew up to 1990, 19:57.298 --> 20:01.948 it's fallen off a little bit here, and then it's predicted to 20:01.945 --> 20:06.585 keep growing for another few years and then it's predicted to 20:06.593 --> 20:07.913 go down here. 20:07.910 --> 20:10.970 I emphasize--guess work--this was not on the original. 20:10.970 --> 20:14.160 This is data, we have fairly decent reason, 20:14.160 --> 20:17.340 but again this error bar is on here and we don't know what 20:17.338 --> 20:20.828 error bars-- how big they should be and this 20:20.827 --> 20:22.747 is really guess work. 20:22.750 --> 20:27.340 The guess work is not too bad for the near future because the 20:27.339 --> 20:32.159 women who are going to have these children are already born, 20:32.160 --> 20:35.510 they're already close to maturity, we know that fertility 20:35.509 --> 20:39.219 rates generally don't change all that fast although I will show 20:39.219 --> 20:42.329 you plenty of exceptions to that in the lecture. 20:42.328 --> 20:46.298 You can maybe more or less believe the next dozen years 20:46.298 --> 20:50.118 here or something like that and then you make various 20:50.119 --> 20:52.639 projections, and I'll show you those 20:52.644 --> 20:55.814 projections can be almost anything because we don't have a 20:55.807 --> 20:57.357 very good basis for that. 20:57.358 --> 21:02.478 The near term projection that the number of people added every 21:02.476 --> 21:07.256 year is going to go up is probably pretty accurate because 21:07.257 --> 21:09.267 it's very near term. 21:09.269 --> 21:14.589 Now, again, the optimists take that data, 21:14.588 --> 21:16.388 that here is the number of people added, 21:16.390 --> 21:19.260 you see it has been going up, it's kind of jiggling around, 21:19.259 --> 21:22.569 and it may or may not decline in the future but because the 21:22.565 --> 21:26.525 base has been growing, because the population keeps 21:26.531 --> 21:29.511 growing, if the same number of people 21:29.512 --> 21:34.032 are added every year then the percentage increase goes down. 21:34.029 --> 21:37.279 So when you hear a lot of optimism about the population 21:37.278 --> 21:42.018 situation, what they're talking about is 21:42.017 --> 21:50.067 that the peak RATE of growth here in the 1960s has come down 21:50.068 --> 21:54.298 as a percentage of the base. 21:54.298 --> 21:57.498 As you just saw, since the base is growing the 21:57.503 --> 22:01.853 number--actual number of people added has not changed all that 22:01.848 --> 22:02.488 much. 22:02.490 --> 22:06.650 Again, we're growing, the world is growing something 22:06.653 --> 22:09.953 1.25%-- 1 to 1.5% a year currently and 22:09.951 --> 22:13.461 the guess work is-- and the hope is that will 22:13.460 --> 22:14.540 continue down. 22:14.538 --> 22:18.408 In fact, this continued decrease is based on some pretty 22:18.410 --> 22:20.170 optimistic assumptions. 22:20.170 --> 22:24.480 We may get time to talk about them later but, 22:24.484 --> 22:27.334 fertility has been falling. 22:27.328 --> 22:30.968 If you presume that fertility has fallen as far as it's going 22:30.973 --> 22:33.833 to fall and now it's going to stay constant, 22:33.828 --> 22:36.238 so the most conservative projection is constant 22:36.240 --> 22:36.870 fertility. 22:36.868 --> 22:40.158 Whatever we are at now that's the way it's going to be, 22:40.163 --> 22:43.343 then you don't get anything like this, you get a huge 22:43.336 --> 22:44.066 takeoff. 22:44.068 --> 22:48.508 This presumes that fertility will keep falling until people 22:48.505 --> 22:52.325 have two children per family and fairly rapidly. 22:52.328 --> 22:55.858 That's a nice guess, a nice prediction, 22:55.862 --> 23:01.442 but we really have essentially no decent theoretical basis to 23:01.439 --> 23:03.019 presume that. 23:03.019 --> 23:06.979 Now here is the one number you should really keep in your mind, 23:06.980 --> 23:12.310 this is right up to date, this is the Census Bureau 2009, 23:12.308 --> 23:15.098 this gives you the world events and it just-- 23:15.098 --> 23:18.378 for being kind of cute it breaks it down to how much is 23:18.380 --> 23:21.910 the increase each year, month, day, you can do it down 23:21.912 --> 23:26.662 to the second and notice-- and I gave you these numbers 23:26.655 --> 23:33.475 last time as ratios as per 1,000 this is the number of births per 23:33.480 --> 23:39.560 year 135 million and the number of deaths 55 million, 23:39.558 --> 23:42.768 so that's the difference, that's the population growth 23:42.767 --> 23:44.277 rate 80 million people. 23:44.279 --> 23:47.739 That's--I think that's one of the key numbers to just keep in 23:47.738 --> 23:49.348 mind, round it off, 23:49.346 --> 23:54.366 80 million that the increase every year on earth now is 80 23:54.374 --> 23:59.494 million and it's been roughly that for quite some time. 23:59.490 --> 24:04.360 The maximum here was something like 90 million, 24:04.363 --> 24:09.453 not quite 90 million, and now we're just about 80 24:09.448 --> 24:10.718 million. 24:10.720 --> 24:13.090 When people say the birth--everything's coming down, 24:13.088 --> 24:15.598 things are getting better, we're going to come to a soft 24:15.597 --> 24:18.077 landing, well what we actually know is 24:18.080 --> 24:21.630 the difference between 87 million and 80 million with 24:21.634 --> 24:25.734 large and unknown error bars so it might not be a decrease at 24:25.733 --> 24:26.353 all. 24:26.349 --> 24:27.659 I mean we just don't know. 24:27.660 --> 24:33.780 Nothing drastic has happened to engender such optimism about the 24:33.782 --> 24:38.412 future of human population, although you will hear that 24:38.406 --> 24:42.196 over and over, and over again. 24:42.200 --> 24:49.780 Now as I showed you, this graph that we are here at 24:49.775 --> 24:56.895 the--actually here to 6.7 billion and all of the 24:56.896 --> 25:04.166 projections show it to continue to increase. 25:04.170 --> 25:07.380 Again the rate of increase gets fuzzier and fuzzier as you go 25:07.378 --> 25:11.078 further out in time, but it will increase, 25:11.077 --> 25:18.127 and the projections are that by 2040 will be nine billion and 25:18.131 --> 25:20.131 still growing. 25:20.130 --> 25:24.630 We're adding a billion at 80 million a year we're adding a 25:24.634 --> 25:26.774 billion every 12.5 years. 25:26.769 --> 25:31.249 If it falls a little bit we'll add a billion every 13 years or 25:31.251 --> 25:35.511 every 14 years and that's to keep in mind when you think of 25:35.512 --> 25:38.992 those numbers, that's a billion people every 25:38.991 --> 25:42.511 12,13, 14 years, pick whatever number you like, 25:42.509 --> 25:43.769 and think of, everybody's green. 25:43.769 --> 25:46.269 Anybody green in this class? 25:46.269 --> 25:48.039 Anybody not green? 25:48.039 --> 25:50.379 Are you environmentalists? 25:50.380 --> 25:53.410 Yes, who's an anti-environmentalist? 25:53.410 --> 25:54.030 Hooray! 25:54.029 --> 25:55.599 One, Two. 25:55.598 --> 26:00.088 Well I'm going to return to this theme but this can't be 26:00.088 --> 26:03.978 repeated enough times, think of the environmental 26:03.981 --> 26:08.401 footprint of a billion extra people every dozen or so years, 26:08.400 --> 26:10.120 a billion extra people. 26:10.118 --> 26:11.838 Now add up all the environmentalism, 26:11.837 --> 26:14.337 all the achievements of this wonderful environmental 26:14.340 --> 26:14.980 movement. 26:14.980 --> 26:18.630 It's a wonderful thing, but it pales in comparison that 26:18.630 --> 26:22.890 it's just we're playing a losing battle with the environment. 26:22.890 --> 26:26.190 As long as we're growing at a billion people in so many years 26:26.186 --> 26:29.536 we are not going to solve the environmental problems no matter 26:29.539 --> 26:32.119 what we do, it's just too great an increase 26:32.116 --> 26:32.716 of people. 26:32.720 --> 26:36.160 Yet, environmentalists generally never talk about human 26:36.161 --> 26:40.021 population; it's too politically dangerous 26:40.019 --> 26:42.039 to talk about that. 26:42.038 --> 26:46.298 Hence in this course one of the very few in the country or 26:46.301 --> 26:50.041 anywhere in the world that really hits--talks about 26:50.040 --> 26:52.060 population straight on. 26:52.058 --> 26:56.838 Why do we--why are we--why is everybody projecting that the 26:56.843 --> 27:00.723 population is going to keep increasing there? 27:00.720 --> 27:05.230 It's simply you look at the age structure and something like 27:05.233 --> 27:09.523 half of the world's population is under 15 years old, 27:09.519 --> 27:13.769 i.e., just coming in--I'm sorry 1/3 of the world's population is 27:13.769 --> 27:17.749 under 15 years old and so just coming into reproductive ages 27:17.749 --> 27:21.589 and we know that for the next-- they will come into 27:21.590 --> 27:26.430 reproductive ages and then be of reproductive potential for the 27:26.425 --> 27:31.105 following 30 years and we know that this increasing number of 27:31.105 --> 27:35.705 now 10 to 15 year olds will be coming into reproductive ages 27:35.705 --> 27:39.055 will keep the population increasing. 27:39.058 --> 27:44.068 It's certain that it will increase although the rate of 27:44.071 --> 27:49.271 increase and how it changes is certainly less certain. 27:49.269 --> 27:55.529 It's under almost any kind of reasonable assumption the 27:55.534 --> 28:02.614 population is going to grow another several billion people. 28:02.608 --> 28:05.338 Again, we're in unprecedented territory, 28:05.338 --> 28:09.738 most people think the earth right now is incredibly stressed 28:09.741 --> 28:14.531 and it is environmental things, situation, and now add another 28:14.525 --> 28:18.865 couple of billion people to that in the near future and see 28:18.866 --> 28:20.286 what's going on. 28:20.288 --> 28:23.118 Since we don't have crystal balls--the students usually ask 28:23.115 --> 28:25.255 me the question, 'what's going to happen?' 28:25.259 --> 28:28.529 I always have to say, 'I left my crystal ball in my 28:28.526 --> 28:29.176 closet.' 28:29.180 --> 28:33.110 I didn't bring it today, I do not have a way into the 28:33.113 --> 28:35.173 future, but anybody who tells you they 28:35.174 --> 28:37.094 know what's going to happen in the future, 28:37.088 --> 28:39.838 and especially if they're going to be optimistic about it, 28:39.839 --> 28:45.489 is a very blind kind of person. 28:45.490 --> 28:50.200 You've all heard discussions of the population problem and it's 28:50.204 --> 28:52.644 really two different problems. 28:52.640 --> 28:56.870 The first problem, which in the West we're very 28:56.865 --> 29:00.535 cognizant of, is over consumption by rich 29:00.538 --> 29:01.548 people. 29:01.548 --> 29:06.388 A good fraction of the world is what you should definitely call 29:06.388 --> 29:09.198 rich and they consume like crazy, 29:09.200 --> 29:12.520 and a lot of what we consume is frivolous like Hummers and great 29:12.519 --> 29:15.179 big-- some little person driving this 29:15.182 --> 29:19.472 great big SUV that they never carry anything heavy and they 29:19.472 --> 29:23.912 certainly don't have to drive over logs or something which an 29:23.911 --> 29:26.131 SUV is actually good for. 29:26.130 --> 29:30.390 The over consumption depletes the world's resources, 29:30.390 --> 29:33.820 increases pollution, destruction of habitat, 29:33.818 --> 29:37.828 etcetera, etcetera, etcetera, so environmental 29:37.833 --> 29:43.723 misery is largely caused by rich people consuming profligately, 29:43.720 --> 29:47.540 unnecessarily and profligately. 29:47.538 --> 29:51.378 The other side of the coin is poverty, 29:51.380 --> 29:55.750 the world is definitely split and the split is getting wider 29:55.747 --> 29:59.537 between poverty and over-- people who over consume - and 29:59.536 --> 30:03.316 their problem of course is under consumption and they lead to all 30:03.323 --> 30:06.933 of the problems of poverty which I have discussed in Hong Kong 30:06.932 --> 30:10.012 and I don't have to tell you very much about what the 30:10.009 --> 30:12.849 problems in the world of poor people are. 30:12.848 --> 30:14.398 We have these two opposite problems, 30:14.400 --> 30:18.320 what I call environmental misery and human misery, 30:18.318 --> 30:22.578 and they're both very largely the result of too rapid 30:22.575 --> 30:26.845 population growth that we might, in some utopian scenario, 30:26.851 --> 30:28.771 eventually be able to cope with, 30:28.769 --> 30:32.979 say the population levels that we have now, maybe. 30:32.980 --> 30:35.590 But, at the rate of growth it's obvious just looking around you 30:35.590 --> 30:37.590 that our technology, our economy, 30:37.594 --> 30:41.654 our governments, have not been able to cope with 30:41.645 --> 30:42.935 this so far. 30:42.940 --> 30:45.820 It's very interesting as a political note that there are 30:45.816 --> 30:48.166 these two faces of the population problem, 30:48.170 --> 30:51.870 the environmental problem and the people misery problem, 30:51.868 --> 30:55.278 and it's amazing how people focus on one or the other. 30:55.279 --> 30:59.029 There's people like--work in planned parenthood and various 30:59.026 --> 31:01.286 feminists and women's organizations, 31:01.286 --> 31:03.866 they're interested in people misery. 31:03.868 --> 31:06.548 They always talk about poverty and its attendant problems. 31:06.548 --> 31:08.288 Then there's the environmentalists and they're 31:08.292 --> 31:10.272 worried about trees and the survival of animals, 31:10.269 --> 31:13.269 and forests, and nature and both are of 31:13.269 --> 31:17.769 course very important and very good causes to work on, 31:17.769 --> 31:20.259 but it is absolutely mind boggling how rarely you find 31:20.258 --> 31:23.128 anybody that's sort of, is really in any way, 31:23.132 --> 31:28.032 concerned about both problems, or in any way realizes how 31:28.029 --> 31:33.249 population is the centerpiece of both of these problems. 31:33.250 --> 31:38.600 Let me talk just a little bit about over consumption and who's 31:38.596 --> 31:42.536 the number one bad guy in over consumption? 31:42.539 --> 31:44.899 We are. 31:44.900 --> 31:49.010 So here's the story for--some of the story for the United 31:49.009 --> 31:49.669 States. 31:49.670 --> 31:57.120 This is the growth of the United States population from 31:57.119 --> 31:59.189 1900 to 2000. 31:59.190 --> 32:06.760 We in 1900 had about 75 million and in 2006 this-- 32:06.759 --> 32:13.799 so in 2006 we passed 300 million people and that's a 32:13.798 --> 32:21.658 quadrupling that our population has quadrupled in that one 32:21.663 --> 32:23.323 century. 32:23.318 --> 32:27.058 We were almost like an underdeveloped country in our 32:27.064 --> 32:28.904 population growth rate. 32:28.900 --> 32:31.460 That is up to the--almost current, 32:31.460 --> 32:35.410 and here is again the latest Census Bureau thing from-- 32:35.410 --> 32:38.810 again this was--just got it out of the computer last night 32:38.805 --> 32:40.895 actually, the latest numbers, 32:40.898 --> 32:44.668 that here's the standard-- one of the standard things is 32:44.672 --> 32:49.792 give you 100 year time frame, currently they're using 1950 to 32:49.785 --> 32:52.505 2050 and we are, as you know, 32:52.507 --> 32:55.137 right about here and here is the U.S. 32:55.137 --> 32:59.377 population growth rate and just almost a perfectly straight 32:59.377 --> 33:00.107 line. 33:00.108 --> 33:03.558 There is no prediction that the U.S. 33:03.563 --> 33:08.993 is going to slow down in its population growth rate, 33:08.990 --> 33:12.320 we are growing at about three million a year, 33:12.318 --> 33:17.868 currently that's 1% of a year, and because of natural increase 33:17.871 --> 33:23.151 that's births over deaths of people already in America, 33:23.150 --> 33:29.130 plus immigration, we're just going here. 33:29.130 --> 33:34.670 In our population growth rate, it's about 2/3 births over 33:34.672 --> 33:40.612 deaths of citizens already here and about 1/3 immigration. 33:40.608 --> 33:45.228 Of immigration, the guesses are that it's about 33:45.233 --> 33:49.843 2/3 legal and 1/3 illegal, obviously the illegal is an 33:49.843 --> 33:51.873 enormous guess, the absolute number, 33:51.868 --> 33:53.788 the percentage of anything that it is, 33:53.788 --> 33:56.808 if you look at how they come up with these numbers it's really 33:56.809 --> 33:57.899 'seat-of-the-pants.' 33:57.900 --> 34:03.420 We don't know very much about the magnitude of illegal 34:03.423 --> 34:08.743 immigration but it's an enormous political issue. 34:08.739 --> 34:13.779 Now on the consumption side, of course we consume so much, 34:13.780 --> 34:19.440 and again numbers vary kind of wildly but the range of numbers 34:19.443 --> 34:24.643 are that an American consumes something between 20 and 40 34:24.644 --> 34:30.314 times what a person in a developing country will consume. 34:30.309 --> 34:34.219 If you multiplied our three million population growth a year 34:34.219 --> 34:37.599 by a consumption factor of 20 that's equivalent-- 34:37.599 --> 34:41.899 a population growth of 60 million poor people and so if 34:41.900 --> 34:47.000 you do it that way it looks like that our population growth is as 34:46.998 --> 34:51.618 damaging to the resource and environmental situation of the 34:51.617 --> 34:55.837 world as the whole rest of world put together, 34:55.840 --> 35:00.000 and that's just considering our population increase not the 34:59.996 --> 35:04.366 population base which is also consuming at this great rate. 35:04.369 --> 35:10.169 We are--indeed it is certainly correct that we are a tremendous 35:10.170 --> 35:15.410 strain on the environment and resources of the earth, 35:15.409 --> 35:17.159 and as I showed you it's not getting better, 35:17.159 --> 35:21.009 our population is just increasing. 35:21.010 --> 35:23.480 You have to balance against that that a lot of our 35:23.481 --> 35:26.361 population growth is of course people coming in from other 35:26.356 --> 35:28.836 countries so that it's not, in some sense, 35:28.844 --> 35:32.034 Americans who are getting richer but its poor people 35:32.030 --> 35:34.030 coming in and getting richer. 35:34.030 --> 35:38.450 You can play these numbers in all different ways and we'll 35:38.445 --> 35:41.385 talk about the politics in a moment. 35:41.389 --> 35:46.519 The U.S. Census Bureau used to say that we will reach--that 35:46.518 --> 35:47.228 the U.S. 35:47.226 --> 35:52.176 population will reach 300 million by the year 2050. 35:52.179 --> 35:56.499 We reached that number 44 years earlier than the Census Bureau 35:56.500 --> 35:58.640 thought, and we are still growing and 35:58.644 --> 36:01.674 now the Census Bureau says there is no sign of stabilization at 36:01.668 --> 36:02.008 all. 36:02.010 --> 36:05.820 They cannot give you a number at which they think the U.S. 36:05.815 --> 36:09.485 population will stabilize, because as far out as anybody 36:09.485 --> 36:13.625 can project, there's no reason to believe that stabilization is 36:13.625 --> 36:14.555 in view. 36:14.559 --> 36:23.729 Now some of the argumentation is that again people-- 36:23.730 --> 36:28.020 this is a very political issue and half the people say, 36:28.018 --> 36:29.818 'it's all those poor people that are over reproducing, 36:29.820 --> 36:32.520 can't they learn some self control?' 36:32.518 --> 36:34.908 Then you have people saying, 'all those Americans and 36:34.914 --> 36:37.544 Japanese that consume like crazy, can't they use some self 36:37.541 --> 36:38.141 control?' 36:38.139 --> 36:42.659 It's an extremely sterile argument that goes on and on and 36:42.664 --> 36:47.194 people don't think beyond two or three sentences into that 36:47.188 --> 36:48.218 argument. 36:48.219 --> 36:52.689 As I'll tell you, if you do it out numerically 36:52.688 --> 36:58.838 the increasing damage is more or less equal and it depends more 36:58.842 --> 37:04.902 critically as Americans usually blame ourselves that we're the 37:04.900 --> 37:08.580 problem, there's a very kind of--I don't 37:08.581 --> 37:12.681 want to use the word racist but a very Euro-Americo centric 37:12.681 --> 37:16.431 argument because the presumption is when it says, 37:16.429 --> 37:19.919 well we're the consumers and--all the poor people, 37:19.920 --> 37:22.700 we don't have to worry about, is that they will stay poor. 37:22.699 --> 37:25.879 It's a Western assumption that poor people are going to stay 37:25.876 --> 37:28.326 poor and they're not-- not only are they not consumers 37:28.333 --> 37:30.283 now, but they're never going to be 37:30.277 --> 37:30.927 consumers. 37:30.929 --> 37:33.029 And that is just nonsense. 37:33.030 --> 37:35.690 We've seen how the Chinese have come up enormously, 37:35.690 --> 37:37.820 the Indians have come up enormously, 37:37.820 --> 37:40.370 the Indonesians have come up enormously, 37:40.369 --> 37:44.389 everywhere in the world these vast numbers of poor people are 37:44.387 --> 37:46.997 now starting to be serious consumers. 37:47.000 --> 37:51.210 I think the CO_2 production in China I think has 37:51.213 --> 37:56.763 just outpaced the United States, but I didn't look that up 37:56.757 --> 37:59.627 recently, and so there are equal 37:59.632 --> 38:03.932 problems, so if one gets out of one's head the idea that poor 38:03.925 --> 38:06.925 people are going to stay poor forever, 38:06.929 --> 38:11.069 which is a pre-globalization idea--now a worker in China can 38:11.072 --> 38:15.492 compete with a worker in America and eventually there's going to 38:15.494 --> 38:16.974 be some leveling. 38:16.969 --> 38:20.179 I think the proper thing is, if you think there are too many 38:20.184 --> 38:22.834 people on earth, for either human misery issues 38:22.829 --> 38:25.029 or environmental misery issues or both, 38:25.030 --> 38:28.030 any birth you should consider more or less equal. 38:28.030 --> 38:31.280 Preventing a birth in America, in Japan, 38:31.280 --> 38:34.560 and Indonesia, everywhere that in the not too 38:34.556 --> 38:39.096 distant future these people are going to be more or less equal 38:39.101 --> 38:43.571 and we'll see in next lecture what the people themselves want 38:43.570 --> 38:46.030 with respect to this thing. 38:46.030 --> 38:51.590 I hope after this course that none of you get involved in the 38:51.590 --> 38:56.500 sterile argument of us versus them, it doesn't get you 38:56.503 --> 38:57.713 anywhere. 38:57.710 --> 39:03.050 In the world as it is today most of the--almost all of the 39:03.045 --> 39:07.535 population growth is in the poorest countries. 39:07.539 --> 39:11.609 Again statistics are pretty bad, there's something like 95% 39:11.614 --> 39:15.134 of population growth in the world is in the poorest 39:15.126 --> 39:16.106 countries. 39:16.110 --> 39:18.850 As you know, new people need schools, 39:18.849 --> 39:20.899 they need healthcare, they need a place to live, 39:20.900 --> 39:24.170 they need jobs and all of this takes money, 39:24.170 --> 39:26.460 takes capital, and that's what the poor 39:26.456 --> 39:29.586 countries are missing, they don't have the capital, 39:29.585 --> 39:32.715 they usually don't have the technological expertise, 39:32.719 --> 39:36.409 they don't have often the quality of government that can 39:36.409 --> 39:40.169 cope with these enormous problems so it's the places that 39:40.166 --> 39:44.326 are least capable of coping with a population increase that are 39:44.327 --> 39:46.337 in fact saddled with it. 39:46.340 --> 39:52.490 The magnitude of this growth is incredible. 39:52.489 --> 39:57.609 As far out as we can project the poor countries are going to 39:57.610 --> 40:01.950 have to build a city equivalent of one million-- 40:01.949 --> 40:07.719 a city to cope with a million people every week for the next 40:07.715 --> 40:11.915 45 years which is as far as we projected. 40:11.920 --> 40:14.630 If you look at--you know the big cities Shanghai, 40:14.630 --> 40:18.680 Beijing and China, just pick almost any name and 40:18.681 --> 40:23.771 go to an almanac and you'll see there's so many mega million 40:23.768 --> 40:27.128 cities in China that-- cities even that I've never 40:27.132 --> 40:28.802 heard of, when you look up their 40:28.804 --> 40:31.844 population, they're in the millions and a place like New 40:31.842 --> 40:34.332 York with seven million people is nothing. 40:34.329 --> 40:38.709 Sweden, where I lived in Sweden for a while, has like seven to 40:38.708 --> 40:40.358 eight million people. 40:40.360 --> 40:45.680 New York City has seven to eight million people, 40:45.681 --> 40:52.701 cities in China that's a small town almost, and India's not far 40:52.704 --> 40:53.954 behind. 40:53.949 --> 40:58.399 People in the United States generally don't have much of an 40:58.402 --> 41:01.552 idea of what poverty really looks like. 41:01.550 --> 41:05.410 One of the best descriptions of this comes from Bill Ryerson who 41:05.407 --> 41:07.917 is going to be a guest lecturer later, 41:07.920 --> 41:11.420 and he describes flying into Bombay, 41:11.420 --> 41:14.050 and this is again a few years back but in this period of 41:14.045 --> 41:16.715 extreme population explosion that we're talking about. 41:16.719 --> 41:19.799 He goes to the airport, and the airport is way outside 41:19.802 --> 41:22.072 the city as all airports have to be, 41:22.070 --> 41:26.200 and by the international flight schedules they come in early in 41:26.197 --> 41:27.127 the morning. 41:27.130 --> 41:29.180 He starts driving in and almost immediately, 41:29.179 --> 41:33.099 at the airport, he starts seeing poor people 41:33.097 --> 41:36.487 begging, on the street you see shanty's 41:36.494 --> 41:38.654 that people are living in. 41:38.650 --> 41:42.690 When he comes into the denser places people start begging and 41:42.693 --> 41:46.203 you see very commonly a mother holding an infant, 41:46.199 --> 41:48.859 and you can look the infant is clearly nearly dead, 41:48.860 --> 41:51.760 and the mother's 'please give me something, 41:51.760 --> 41:54.630 anything so that I can keep this child alive until 41:54.626 --> 41:57.316 tomorrow,' and there's one after the other, 41:57.320 --> 41:58.990 after the other and it gets denser. 41:58.989 --> 42:01.639 And then the sun comes up and it gets warm, 42:01.639 --> 42:06.109 India's generally a rather warm country and there's all these 42:06.108 --> 42:09.538 jitney's and motorbikes, and trucks, small trucks 42:09.543 --> 42:13.283 putting around and they don't have good catalytic converters, 42:13.280 --> 42:15.800 those are expensive because a lot of them have platinum in 42:15.804 --> 42:18.164 them, so they produce a lot of 42:18.159 --> 42:23.409 pollution and the air gets very thick with this black smoke very 42:23.407 --> 42:25.807 early-- black soot whatever you want to 42:25.806 --> 42:29.036 call it in the early morning so you're not breathing fresh air. 42:29.039 --> 42:32.329 And then of course they have no toilets around, 42:32.329 --> 42:35.629 and you're going to read some articles about what that means, 42:35.630 --> 42:38.750 and so very soon the stench of human waste-- 42:38.750 --> 42:41.190 you're on a main street going into the main city, 42:41.190 --> 42:46.990 the stench of human waste comes up at you and it smells terribly 42:46.990 --> 42:52.060 and more and more beggars and it's just absolutely heart 42:52.056 --> 42:56.196 wrenching description of what's going on. 42:56.199 --> 43:00.659 And then you think that here are millions and millions of 43:00.655 --> 43:05.265 people that will never have a real house, they live in some 43:05.271 --> 43:07.661 cardboard shack somewhere. 43:07.659 --> 43:11.239 They'll never have a real job, they'll never probably go to 43:11.240 --> 43:15.280 the bathroom in a toilet, and they may never even breathe 43:15.280 --> 43:19.930 a breath of fresh air, so poverty is really a very, 43:19.931 --> 43:26.171 very serious kind of situation and you can go to lots and lots 43:26.166 --> 43:32.706 of cities in the world and see similar kinds of descriptions. 43:32.710 --> 43:37.300 Now to do the numbers on this poverty, so we compare it to the 43:37.297 --> 43:40.457 United States, so General Motors before its 43:40.456 --> 43:41.806 recent demise. 43:41.809 --> 43:45.949 These numbers are three or four years old, 43:45.949 --> 43:48.759 so they pay wages to the workers, then they have health 43:48.755 --> 43:51.915 benefits which you've read about as very high because they pay 43:51.923 --> 43:54.993 them for the rest of their life and they pay pensions, 43:54.989 --> 43:58.039 so when you add all that up how much lifetime they're going to 43:58.039 --> 44:00.839 pay for a worker and divide it by the number of hours the 44:00.840 --> 44:05.480 worker works, it comes out for General Motors 44:05.478 --> 44:12.228 was $80 an hour and that was somewhere near a maximum for 44:12.230 --> 44:15.980 union wages, not counting like airline 44:15.981 --> 44:19.191 pilots who get an awful lot more than that. 44:19.190 --> 44:23.460 The upper middle class--that's blue-collar workers at GM-- 44:23.460 --> 44:28.060 the upper middle class people mostly in this room are going to 44:28.063 --> 44:31.163 be earning an awful lot more than that. 44:31.159 --> 44:35.659 On the other hand is the poverty level which for a family 44:35.663 --> 44:41.393 of a mother, father, and three children is 44:41.391 --> 44:47.361 defined as $24,000 a year, that's the 2006 number, 44:47.364 --> 44:48.624 the official U.S. 44:48.619 --> 44:53.079 number which is $13.35 a day per person, that's the poverty 44:53.083 --> 44:57.013 level as officially defined in the United States. 44:57.010 --> 45:03.450 Wal-Mart, a worker, a sales associate earns $6.10 45:03.449 --> 45:10.709 an hour or $12,000 a year-- $6.00 an hour--is $12,000 a 45:10.708 --> 45:17.948 year they are below poverty level so the next step UP for a 45:17.945 --> 45:24.055 Wal-Mart worker is the official poverty level. 45:24.059 --> 45:28.789 When you go to developing countries you have to cut--to 45:28.788 --> 45:34.298 get any idea of a scale you have to cut the Wal-Mart wages by at 45:34.304 --> 45:36.674 least a factor of four. 45:36.670 --> 45:43.390 Wal-Mart makes its pants in El Salvador and the pants sell for, 45:43.389 --> 45:48.299 in this particular article, on this $16.95 in their United 45:48.304 --> 45:51.724 States stores, and how much do you think the 45:51.715 --> 45:55.335 women in El Salvador get to make the pants, per pant? 45:55.340 --> 46:04.400 15 cents is the wage level that they get for it. 46:04.400 --> 46:09.400 The UN reported that about half of the world's workers, 46:09.396 --> 46:14.576 which is about 1.4 billion people, earn less than $2.00 a 46:14.579 --> 46:15.319 day. 46:15.320 --> 46:20.440 The average wage, the median wage in the world is 46:20.443 --> 46:23.543 something like $2.00 a day. 46:23.539 --> 46:25.269 That's per wage earner, not per family, 46:25.268 --> 46:28.878 not per person, but per wage earner and that 46:28.882 --> 46:33.592 then has to be divided among however many dependents that 46:33.588 --> 46:34.848 person has. 46:34.849 --> 46:36.389 I've told you that what the U.S. 46:36.394 --> 46:38.494 sets as its official level for poverty, 46:38.489 --> 46:42.389 every country in the world of course gets to decide its own 46:42.387 --> 46:46.667 level of what poverty is, and the official poverty level 46:46.670 --> 46:52.520 in the poorest ten to 20-- poorest 20 countries is $1.25. 46:52.518 --> 46:56.018 You're only poor if you earn less than a $1.25 per capita, 46:56.016 --> 46:56.626 per day. 46:56.630 --> 47:02.420 In both China and India the official poverty level is closer 47:02.422 --> 47:06.842 to $1.00 a day and this is at 2005 prices, 47:06.840 --> 47:11.140 again statistics are always a couple of years behind things. 47:11.139 --> 47:15.219 In rich places like Latin America and Eastern Europe $2.00 47:15.224 --> 47:19.384 a day is the more appropriate poverty level and that is for 47:19.382 --> 47:24.312 all the developing countries, $2.00 a day is the median, 47:24.309 --> 47:27.949 their own self-defined poverty level. 47:27.949 --> 47:31.759 Within each country and each region there's great inequality 47:31.762 --> 47:34.912 of course in income, so about 1/3 of the people in 47:34.911 --> 47:37.891 Latin America are living on less than $2.00 a day, 47:37.889 --> 47:41.769 2/3 of the people of Pakistan live on less than 2/3-- 47:41.768 --> 47:45.608 $2.00 a day, but more than 58% of the 47:45.608 --> 47:51.258 population in Kenya lives on less than $1.00 a day; 47:51.260 --> 47:55.210 Brazil 25% of the people on less than $1.00 a day; 47:55.210 --> 47:59.000 the whole of Sub-Saharan Africa 44% of the people on less than 47:59.001 --> 48:02.301 $1.00 a day and it's not only these traditionally poor 48:02.297 --> 48:04.627 countries, but in Romania, 48:04.625 --> 48:07.875 after the Soviet bloc fell apart, 48:07.880 --> 48:10.780 40% of the people live on less than $1.00 a day. 48:10.780 --> 48:16.410 Indonesia had a government work program so that people could get 48:16.409 --> 48:21.769 some kind of work and laborers got $0.75 a day for five hours 48:21.771 --> 48:25.451 of work a day, that's $0.15 an hour. 48:25.449 --> 48:29.209 I don't know how much time it takes to sew Wal-Mart pants but 48:29.213 --> 48:32.443 maybe an hour, probably less but--so $.15 an 48:32.443 --> 48:36.183 hour is a wage that for many people in a place like 48:36.175 --> 48:38.845 Indonesia, which has a lot of oil, 48:38.849 --> 48:41.969 it's not overall necessarily a poor place, 48:41.969 --> 48:49.379 $0.15 an hour for an hour's work; 48:49.380 --> 48:53.260 $0.75 a day and that's much more than they can get 48:53.264 --> 48:58.024 working--getting agricultural jobs around where they live. 48:58.018 --> 49:03.868 Here's a description from Zambia, a nine-year-old boy, 49:03.871 --> 49:08.071 Alone Banda, his job is to be beat rock 49:08.068 --> 49:10.938 fragments into powder. 49:10.940 --> 49:14.090 He doesn't have a hammer, he found a large steel bolt 49:14.085 --> 49:16.805 from some construction site, he found a bolt, 49:16.813 --> 49:19.753 he grips in his bare hand and pounds the rock with it. 49:19.750 --> 49:23.560 He takes raw rock, takes a bolt that he found and 49:23.559 --> 49:29.639 pounds with it and he can fill-- it takes him about a--in a week 49:29.639 --> 49:35.959 he can fill about half a bag with this powder which is used 49:35.963 --> 49:42.513 for construction and he gets about $1.50 for the half bag and 49:42.505 --> 49:48.715 it's used for making concrete in Kenya for instance. 49:48.719 --> 49:50.209 Children start working at five or six-- 49:50.210 --> 49:53.640 we saw--we talked about Charles Dickens who so much of his 49:53.635 --> 49:57.055 writing was about children going to work at age seven, 49:57.059 --> 49:59.489 while seven is old, they go to five and six and 49:59.492 --> 50:01.822 they work as prostitutes even at that age; 50:01.820 --> 50:04.980 minors, construction workers, pesticide sprayers, 50:04.980 --> 50:08.140 all the kinds of dangerous and miserable jobs. 50:08.139 --> 50:12.269 In Sub-Saharan Africa there's something like 48 million 50:12.269 --> 50:15.559 children 14 and younger who are working, 50:15.559 --> 50:20.929 and four years later it says, by 2004 it had increased by 1.3 50:20.925 --> 50:24.945 million, so the number of children 50:24.954 --> 50:32.264 working at these poverty level jobs is increasing because the 50:32.264 --> 50:37.994 whole population is increasing and so forth. 50:37.989 --> 50:41.309 This is the poverty rates around the world and just 50:41.309 --> 50:44.829 compare-- this confirms the numbers that 50:44.833 --> 50:50.053 I'm telling you that these are the headcount in number of 50:50.048 --> 50:54.078 millions, the percent below poverty line 50:54.081 --> 50:58.101 at $1.25 a day, less than $2.00 a day, 50:58.099 --> 51:02.479 and if you take out China, China is still one of the 51:02.476 --> 51:05.066 poorest places when you add in all the peasants, 51:05.070 --> 51:08.710 it doesn't get--it gets some--actually China makes it 51:08.710 --> 51:11.340 worse, when you add in China you have 51:11.340 --> 51:14.410 a higher percentage at these poverty levels, 51:14.409 --> 51:17.479 same for whatever poverty level you want to work. 51:17.480 --> 51:24.270 These are the appropriate poverty levels for developing 51:24.269 --> 51:25.779 countries. 51:25.780 --> 51:30.220 Now, again you have the same two ways of describing this-- 51:30.219 --> 51:33.299 the absolute number of people in this kind of poverty is 51:33.295 --> 51:35.615 growing up, so as the whole population 51:35.621 --> 51:39.001 grows the number people in these levels are growing up, 51:39.000 --> 51:42.350 yet there has been economic progress in the sense that, 51:42.349 --> 51:47.129 as a percentage of people, the poverty numbers are going 51:47.125 --> 51:49.465 down, so there's more people in 51:49.474 --> 51:52.914 poverty, but there's a lesser percentage of the total 51:52.914 --> 51:54.574 population in poverty. 51:54.570 --> 51:56.890 Again, you can, depending on your political 51:56.891 --> 51:59.211 orientation, you can describe this as an 51:59.208 --> 52:02.738 increasingly bad situation where more and more people are in this 52:02.737 --> 52:05.817 kind of poverty, or a situation that is getting 52:05.818 --> 52:10.168 better because the percentage of people in poverty is going down. 52:10.170 --> 52:17.600 Now the miracle--so you've all heard of the economic miracle in 52:17.601 --> 52:20.361 East Asia especially. 52:20.360 --> 52:26.340 Anybody come fairly recently from China? 52:26.340 --> 52:28.540 None of the students come from China. 52:28.539 --> 52:31.189 Well the average income, and again, 52:31.190 --> 52:34.000 income how you define--of course the Chinese don't earn 52:34.000 --> 52:37.230 dollars so when you express it in dollars there's a translation 52:37.226 --> 52:40.086 and the best way of doing it is what's called PPP, 52:40.090 --> 52:41.740 purchasing power parity. 52:41.739 --> 52:44.389 One way is to use the official exchange rate, 52:44.393 --> 52:47.773 how many--they earn so many Yuan and how many dollars can 52:47.771 --> 52:49.461 they buy with that Yuan? 52:49.460 --> 52:51.610 That exchange rate, as you know especially in 52:51.608 --> 52:54.338 China, is manipulated by the government and is not a real 52:54.342 --> 52:54.882 number. 52:54.880 --> 52:58.320 A number that makes the Chinese income look more favorable and 52:58.322 --> 53:01.712 is closer to a real number is what they call purchasing power 53:01.708 --> 53:02.328 parity. 53:02.329 --> 53:05.259 You say how much does a sack of rice cost in China, 53:05.260 --> 53:07.580 how much does it cost in the United States, 53:07.579 --> 53:11.849 and you try to use a basket of commodities appropriate to what 53:11.849 --> 53:15.699 the people in that country actually use and say how much 53:15.699 --> 53:19.619 would that cost in dollars so you can have a parity. 53:19.619 --> 53:23.619 On that kind of a level, a Chinese peasant on average 53:23.617 --> 53:25.307 earns a $1.00 a day. 53:25.309 --> 53:31.799 The person--a $1.00 is the average income in the Chinese 53:31.802 --> 53:33.812 peasant family. 53:33.809 --> 53:36.659 The jobs in the modern sector, which means one of these 53:36.659 --> 53:39.299 manufacturing jobs, and they migrate to some city, 53:39.298 --> 53:42.258 they live in these dorm rooms where they're just stacked like 53:42.259 --> 53:44.849 cord wood, and they basically have no free 53:44.847 --> 53:47.787 time and they're-- it's a miserable life but they 53:47.786 --> 53:49.026 double their income. 53:49.030 --> 53:54.700 The economic miracle in Asia is when people go from $1.00 a day 53:54.695 --> 53:57.905 to $2.00 a day, and there's hundreds of 53:57.907 --> 54:01.277 millions of people, you add up China and India, 54:01.280 --> 54:05.660 hundreds of millions of people who are desperate to earn $2.00 54:05.663 --> 54:08.633 a day; it's a doubling of their income. 54:08.630 --> 54:09.770 When you read these horrible stories, 54:09.768 --> 54:13.128 horrible to our ears, of how, especially women, 54:13.130 --> 54:15.680 moving into the big cities Guangdong, 54:15.679 --> 54:18.679 Canton or any of the big cities, how they're living and 54:18.677 --> 54:20.897 the conditions they're working under, 54:20.900 --> 54:23.350 remember it represents a doubling of their income and 54:23.353 --> 54:27.233 it's so much-- they can send most of that back 54:27.228 --> 54:33.368 to their home village and home villages are all living on this 54:33.367 --> 54:35.177 kind of income. 54:35.179 --> 54:39.149 When we talk about poverty--we will later talk about population 54:39.146 --> 54:43.106 in China - you must realize that basically all of those workers 54:43.112 --> 54:46.502 who now have access to moderately decent education can 54:46.501 --> 54:47.911 compete with us. 54:47.909 --> 54:51.179 There's very few jobs that we can do and they can't do, 54:51.179 --> 54:54.679 and so we at up to $80 an hour for a blue collar worker are 54:54.675 --> 54:58.165 basically in competition with someone who's very happy-- 54:58.170 --> 55:00.870 and they grumble, people working for GM grumble, 55:00.869 --> 55:04.079 and in some of their conditions the grumbling could be quite 55:04.083 --> 55:07.143 fair-- but they're in competition with 55:07.143 --> 55:11.373 people earning $2.00, that wish they would earn $2.00 55:11.365 --> 55:11.875 a day. 55:11.880 --> 55:18.320 In places--this is not only our competition but jewelry making, 55:18.320 --> 55:22.450 very labor intensive--of course countries with low wage rates 55:22.449 --> 55:26.509 attract very labor intensive jobs and hand making of jewelry 55:26.510 --> 55:28.850 is a very labor intensive job. 55:28.849 --> 55:32.369 Sure enough, Bangkok was one of the centers 55:32.369 --> 55:35.389 of jewelry making, and because it was the center 55:35.385 --> 55:37.155 and it requires a fair amount of skill, 55:37.159 --> 55:41.589 the wages actually rose in Bangkok for these jewelry makers 55:41.586 --> 55:46.546 and they got up to $8.00 a day for a jewelry worker in Bangkok. 55:46.550 --> 55:48.260 Guess what happened? 55:48.260 --> 55:51.430 All the factories moved to China, they're back down to 55:51.429 --> 55:54.479 $2.00 a day, a saving of 75% on your labor costs; 55:54.480 --> 55:55.870 of course they're going to do it. 55:55.869 --> 55:59.499 Not only in China, but Mexico, all the 55:59.500 --> 56:03.100 maquiladoras, the border between Texas and 56:03.096 --> 56:07.296 California and Mexico has a lot of factories and because of 56:07.295 --> 56:11.345 various trade laws they can assemble things and just ship 56:11.349 --> 56:16.199 them across the border with low trade tariffs and everything, 56:16.199 --> 56:20.739 and they have been nearly wiped out with jobs moving to China. 56:20.739 --> 56:22.589 Now of course, for a while anyway, 56:22.585 --> 56:25.605 conditions were getting a little bit better in China so 56:25.608 --> 56:26.838 the jobs moved to? 56:26.840 --> 56:28.990 Anyone reading the newspapers? 56:28.989 --> 56:32.559 Who's now competing with China? 56:32.559 --> 56:35.529 India, at a high level, but Vietnam, 56:35.525 --> 56:40.605 Cambodia, places that are even poorer than China are now even 56:40.608 --> 56:43.318 taking jobs away from China. 56:43.320 --> 56:49.570 In Romania, which is one of the poorest countries in Europe, 56:49.565 --> 56:55.805 the wages average about $83.00 a week, so $10.00 or $12.00 a 56:55.813 --> 56:56.663 day. 56:56.659 --> 57:00.809 When they got into the European Union what did the Romanian 57:00.809 --> 57:01.739 workers do? 57:01.739 --> 57:05.859 They moved out to France, Germany, England to get the 57:05.864 --> 57:10.704 higher wages that are available there which left a lot of jobs 57:10.704 --> 57:15.394 unfilled in Romania where they get $12.00 a day as I've just 57:15.387 --> 57:16.257 said. 57:16.260 --> 57:18.910 What did the Romanians do? 57:18.909 --> 57:21.739 Imported Chinese, who worked for less and filled 57:21.744 --> 57:24.464 the jobs, there's an unlimited number of 57:24.463 --> 57:28.253 peasants in China that would love to work in Romania under 57:28.250 --> 57:31.580 almost any kind of conditions, and they leave their husbands, 57:31.581 --> 57:34.311 their children, everybody is left home usually 57:34.311 --> 57:38.481 under the care of grandparents who are too old themselves to 57:38.483 --> 57:39.053 work. 57:39.050 --> 57:44.670 Keep that in mind, abject poverty is a $1.00 a 57:44.668 --> 57:50.038 day, the economic miracle is $2.00 a day. 57:50.039 --> 57:56.459 Okay, what does living look like in these places? 57:56.460 --> 57:59.850 We've been talking about Bombay, and Shanghai, 57:59.846 --> 58:03.606 these are big places that everybody knows about. 58:03.610 --> 58:06.480 You'll never guess where this is and you've probably never 58:06.476 --> 58:07.176 heard of it. 58:07.179 --> 58:09.139 This is the capital of Mauritania. 58:09.139 --> 58:11.799 How many know where Mauritania is? 58:11.800 --> 58:14.130 Good, it's on the Atlantic coast of Africa. 58:14.130 --> 58:17.670 I should remember to always make a slide--geography map 58:17.668 --> 58:19.108 slides but I didn't. 58:19.110 --> 58:22.670 It's on the Atlantic coast it is--the capital is a place 58:22.666 --> 58:23.956 called Nouakchott. 58:23.960 --> 58:28.010 Nouakchott is over there somewhere and this is the 58:28.007 --> 58:32.547 suburbs of Nouakchott and what it is is desert it's-- 58:32.550 --> 58:36.270 all of Mauritania is basically desert, 58:36.268 --> 58:38.758 until it rolls into the ocean in which case it becomes an 58:38.762 --> 58:39.122 ocean. 58:39.119 --> 58:44.889 In the desert all these people live in shanties of any kind of 58:44.891 --> 58:48.961 construction material that they can find. 58:48.960 --> 58:52.150 The national government, the city government does not 58:52.152 --> 58:55.532 have the resources to deal with these people at all, 58:55.530 --> 58:59.350 so they get no sanitation, they get no policing, 58:59.349 --> 59:02.969 they get no water, there's just--these are called 59:02.972 --> 59:07.732 unplanned communities and they sort of basically don't exist. 59:07.730 --> 59:09.640 What are they to the government? 59:09.639 --> 59:12.739 They're a source of problems because very poor people, 59:12.737 --> 59:15.657 who have nothing to lose, revolt every so often. 59:15.659 --> 59:18.189 They say you've got something, we don't have it, 59:18.190 --> 59:21.120 we want it, why is the government not doing anything 59:21.115 --> 59:23.745 for us, so this is a source of social 59:23.746 --> 59:26.346 discontent, and the shanty towns are around 59:26.347 --> 59:29.267 every big city in the world are great sources of social 59:29.271 --> 59:30.031 discontent. 59:30.030 --> 59:32.970 What you see here is a road, and I've just said they 59:32.974 --> 59:34.654 basically don't have roads. 59:34.650 --> 59:37.780 What happens is that the military in each of these 59:37.777 --> 59:41.797 countries wants to be sure to be able to control the people, 59:41.800 --> 59:44.230 so every so often they send in a bulldozer, 59:44.230 --> 59:48.440 you can sort of see another road here off to the right. 59:48.440 --> 59:52.420 Let me get a better one of these--they just come in one 59:52.422 --> 59:56.702 morning and the people are asleep in their shanty's because 59:56.699 --> 59:58.839 they don't have any jobs. 59:58.840 --> 1:00:02.210 And very early in the morning they just hear this rumble and 1:00:02.210 --> 1:00:05.640 they walk outside to find out what it is and the bulldozer is 1:00:05.639 --> 1:00:08.949 two minutes away from their house and they just go down and 1:00:08.952 --> 1:00:11.412 knock out anything that's in the way. 1:00:11.409 --> 1:00:14.929 If you happen to be in the path that the military bulldoze 1:00:14.931 --> 1:00:17.491 knocks down, well sorry, sorry, 1:00:17.489 --> 1:00:21.109 that's gone, and then the soldiers can go 1:00:21.114 --> 1:00:23.384 into these situations. 1:00:23.380 --> 1:00:28.490 The point being that these enormous dense populations, 1:00:28.489 --> 1:00:31.809 which we associate with Calcutta or Bombay, 1:00:31.809 --> 1:00:35.689 or Shanghai, Canton, are in fact almost 1:00:35.690 --> 1:00:40.390 everywhere in the world now including this-- 1:00:40.389 --> 1:00:45.179 this is where Nouakchott meets the Atlantic Ocean. 1:00:45.179 --> 1:00:49.169 Here's the Atlantic Ocean there, and what do they live on? 1:00:49.170 --> 1:00:53.240 Well they live on fishing and each of these little things 1:00:53.237 --> 1:00:56.067 here, if you can see, is a fishing boat, 1:00:56.070 --> 1:00:59.340 a little boat that they row out and fish. 1:00:59.340 --> 1:01:02.370 Look at how many boats there are, all trying to get an 1:01:02.369 --> 1:01:05.969 occasional fish and that's not a terribly rich fishing ground of 1:01:05.969 --> 1:01:06.769 the world. 1:01:06.768 --> 1:01:10.088 It's very close to the equator and there's no big upwelling of 1:01:10.085 --> 1:01:13.125 nutrients, there's not a great big fishing down there. 1:01:13.130 --> 1:01:17.940 This is how the people have been competing with each other 1:01:17.942 --> 1:01:21.152 for the few fish that are out there. 1:01:21.150 --> 1:01:24.180 Now--so that's the desert and here is the jungle. 1:01:24.179 --> 1:01:29.619 This is Brazil in a place that you may have heard of Serra 1:01:29.615 --> 1:01:32.085 Pelada, peeled mountain or naked 1:01:32.094 --> 1:01:35.974 mountain, anybody who has heard of it or seen pictures of this 1:01:35.974 --> 1:01:36.614 before? 1:01:36.610 --> 1:01:39.400 One--a couple of people, it's very well known, 1:01:39.400 --> 1:01:42.720 so if you travel in Brazil all the big cities again have shanty 1:01:42.717 --> 1:01:45.817 towns where people are desperate for some kind of a job. 1:01:45.820 --> 1:01:49.560 Every so often a truck rolls through and says, 1:01:49.559 --> 1:01:51.769 I have some jobs, and people just pile in, 1:01:51.768 --> 1:01:54.278 and I've watched it, and they don't ask how much, 1:01:54.280 --> 1:01:56.810 where am I going, what's the kind of work; 1:01:56.809 --> 1:02:00.009 a job is like a magic word, it's like manna from heaven, 1:02:00.005 --> 1:02:01.455 they jump in the truck. 1:02:01.460 --> 1:02:05.260 Well one of the places you're taken to is this place, 1:02:05.260 --> 1:02:07.000 and this place is way in the middle of the jungle, 1:02:07.000 --> 1:02:11.440 like 1,000 miles from Rio or Sao Paolo and what it is, 1:02:11.440 --> 1:02:14.450 it's a mountain that they found gold in. 1:02:14.449 --> 1:02:18.169 Normally if you've seen like mining in the western United 1:02:18.166 --> 1:02:22.006 States they have these steam shovels which have a bucket as 1:02:22.014 --> 1:02:27.374 big as this whole room probably, and each drag of the bucket 1:02:27.365 --> 1:02:33.055 pulls up hundreds of tons, I don't know the actual numbers. 1:02:33.059 --> 1:02:38.329 In Serra Pelada, human labor is cheaper than to 1:02:38.331 --> 1:02:40.741 buy a steam shovel. 1:02:40.739 --> 1:02:44.399 What each of these little dots are is a person. 1:02:44.400 --> 1:02:45.060 What it is? 1:02:45.063 --> 1:02:48.263 This is a pit and they're digging in the mud there, 1:02:48.260 --> 1:02:51.750 they carry the mud up--the sluicing is up here on the top 1:02:51.746 --> 1:02:54.576 where they have-- sluicing is--gold is heavier 1:02:54.577 --> 1:02:57.317 than soil so they take, basically mud, 1:02:57.324 --> 1:03:01.054 dump it into someplace, water runs over it, 1:03:01.050 --> 1:03:04.510 washes away the mud, and anything that sticks down 1:03:04.507 --> 1:03:07.817 falls heavy in little flakes or tiny nuggets of gold; 1:03:07.820 --> 1:03:11.230 that's the primitive way of doing gold mining. 1:03:11.230 --> 1:03:14.390 Just flow water over mud and there's very, 1:03:14.394 --> 1:03:18.414 very low concentration you get a gold flake there. 1:03:18.409 --> 1:03:21.679 What do these people--how do they work? 1:03:21.679 --> 1:03:26.199 This is--they go down, then climb--these are wooden 1:03:26.195 --> 1:03:29.155 ladders, and another part they climb 1:03:29.163 --> 1:03:33.553 down the ladders and they have burlap sacks on their back, 1:03:33.550 --> 1:03:36.140 the cheapest kind of sack, and they go down and with very 1:03:36.139 --> 1:03:38.219 primitive implements or maybe their hands, 1:03:38.219 --> 1:03:41.269 they take the earth from the bottom of the pit, 1:03:41.268 --> 1:03:44.488 they put it in these packs, they put the pack on their back 1:03:44.485 --> 1:03:47.525 and they climb up the stairs and dump it into the sluice 1:03:47.534 --> 1:03:49.534 apparatus and then go back down. 1:03:49.530 --> 1:03:51.360 That's their whole life. 1:03:51.360 --> 1:03:53.580 There are miserable wages, they can't leave because 1:03:53.583 --> 1:03:56.033 they're in the middle of the jungle, they have no way of 1:03:56.029 --> 1:03:58.029 getting back to any kind of civilization. 1:03:58.030 --> 1:04:00.520 The companies do indeed provide prostitutes for them. 1:04:00.518 --> 1:04:03.218 This whole village is full of prostitutes which are the women 1:04:03.215 --> 1:04:04.785 that come out the same situation. 1:04:04.789 --> 1:04:08.419 Send a truck around and say they have jobs for women, 1:04:08.418 --> 1:04:11.838 they jump on with little or no questions asked. 1:04:11.840 --> 1:04:15.020 How is the whole thing kept under control? 1:04:15.018 --> 1:04:19.278 By soldiers with guns or paramilitaries with guns, 1:04:19.280 --> 1:04:25.150 and here is moderately typical, one of the workers has not even 1:04:25.152 --> 1:04:29.112 the clothes on his back, and there's huge numbers of 1:04:29.106 --> 1:04:30.916 them and they are kept in control. 1:04:30.920 --> 1:04:34.170 In this particular instance the things were looking like they 1:04:34.168 --> 1:04:36.008 were going to go out of control. 1:04:36.010 --> 1:04:45.210 Again, this is all around the world you'll find situations 1:04:45.211 --> 1:04:47.151 like this. 1:04:47.150 --> 1:04:55.780 1:04:55.780 --> 1:04:59.230 Sometimes I talk about--everywhere in the world. 1:04:59.230 --> 1:04:59.950 If you go up to Mt. 1:04:59.947 --> 1:05:01.907 Everest--we've got--what are the ends of the earth? 1:05:01.909 --> 1:05:04.249 There's the deserts, there's the jungles, 1:05:04.251 --> 1:05:05.131 and there's Mt. 1:05:05.128 --> 1:05:08.168 Everest and I just copied down some statistics on Mt. 1:05:08.172 --> 1:05:11.452 Everest, how much population there is in the world. 1:05:11.449 --> 1:05:16.639 There's--up high, and I used to mountain climb a 1:05:16.637 --> 1:05:18.847 lot, a single footstep can require 1:05:18.847 --> 1:05:21.597 eight breaths, you take a step you pant eight 1:05:21.597 --> 1:05:23.857 times, and people like me it would be 1:05:23.858 --> 1:05:25.538 a lot more than eight times. 1:05:25.539 --> 1:05:28.439 On one particular day, and standard in the couple of 1:05:28.436 --> 1:05:31.846 months that you can climb it, there's 500 climbers waiting to 1:05:31.846 --> 1:05:33.036 climb up Everest. 1:05:33.039 --> 1:05:37.439 The place is just littered with dead bodies, it's littered with 1:05:37.440 --> 1:05:39.220 oxygen bottles, I mean Mt. 1:05:39.215 --> 1:05:43.185 Everest is kind of a congestion zone, it looks like Grand 1:05:43.190 --> 1:05:47.590 Central Station that have been sort of cleared out of people on 1:05:47.592 --> 1:05:48.872 many days. 1:05:48.869 --> 1:05:52.569 There's 120 dead bodies littering the top of Mt. 1:05:52.567 --> 1:05:57.047 Everest, so population has gotten so extreme that it's not 1:05:57.050 --> 1:06:00.980 only the big cities, it's basically everywhere that 1:06:00.983 --> 1:06:03.033 you look people are. 1:06:03.030 --> 1:06:08.720 Let's just conclude today with a little bit of future guessing. 1:06:08.719 --> 1:06:13.559 We know that fertility--so now we have most of the world at a 1:06:13.561 --> 1:06:18.161 very high fertility rate, population going gangbusters. 1:06:18.159 --> 1:06:22.249 Now can we dream up a scenario where this gets better? 1:06:22.250 --> 1:06:24.590 It may get better, it may not get better, 1:06:24.590 --> 1:06:27.310 things may get worse until there's some incredible crisis 1:06:27.306 --> 1:06:29.146 or things may stay as they are now, 1:06:29.150 --> 1:06:32.810 or things may coast to a soft landing, 1:06:32.809 --> 1:06:33.289 we don't know. 1:06:33.289 --> 1:06:40.029 Let's draw ourselves a scenario for the soft landing situation. 1:06:40.030 --> 1:06:42.770 One of the things that we know is that there's very, 1:06:42.768 --> 1:06:45.258 very poor people, these $1.00 a day people don't 1:06:45.257 --> 1:06:48.377 limit their births and the exact reason for it we'll discuss 1:06:48.380 --> 1:06:48.910 later. 1:06:48.909 --> 1:06:50.369 A lot of it has to do with education, 1:06:50.369 --> 1:06:52.789 that they don't--a lot of things about how their bodies 1:06:52.786 --> 1:06:55.736 work they don't understand, so they're afraid of modern 1:06:55.737 --> 1:06:59.627 contraception, a lot of issues which we will 1:06:59.628 --> 1:07:00.538 discuss. 1:07:00.539 --> 1:07:04.399 We observe around the world that some increase in standard 1:07:04.398 --> 1:07:06.768 of living has to take place for-- 1:07:06.768 --> 1:07:12.508 before people start being willing and want to limit their 1:07:12.510 --> 1:07:13.740 fertility. 1:07:13.739 --> 1:07:17.259 Let's take the minimum situation, let's say someone 1:07:17.255 --> 1:07:20.695 gets one of these $2.00 a day jobs and that's-- 1:07:20.699 --> 1:07:24.469 then they start thinking differently about themselves in 1:07:24.469 --> 1:07:26.319 the world, they may be in the city where 1:07:26.324 --> 1:07:28.784 they get some education, some awareness of what's going 1:07:28.782 --> 1:07:31.062 on in the world, they want to limit their 1:07:31.061 --> 1:07:34.421 population so let's say that we go from $1.00 a day to $2.00 a 1:07:34.418 --> 1:07:36.508 day, that's incredibly optimistic 1:07:36.505 --> 1:07:40.085 that $2.00 a day is sufficient but you'll see what-- where I'm 1:07:40.090 --> 1:07:40.620 going. 1:07:40.619 --> 1:07:42.829 That's a doubling of income of the poor people. 1:07:42.829 --> 1:07:45.529 Again, something like a third of the people on earth are in 1:07:45.530 --> 1:07:49.680 this $1.00 to $2.00 a day range, so you double their income and 1:07:49.681 --> 1:07:54.811 all of sudden miracles happen and population stops growing, 1:07:54.809 --> 1:07:57.739 not real, way overly optimistic. 1:07:57.739 --> 1:08:01.639 Another thing that we know is that when incomes around the 1:08:01.639 --> 1:08:05.809 world rise the poor people have the smallest rise and the rich 1:08:05.811 --> 1:08:08.071 people have the biggest rise. 1:08:08.070 --> 1:08:10.970 If the small people are doubling their income, 1:08:10.965 --> 1:08:13.985 what is the average of the whole world doing? 1:08:13.989 --> 1:08:15.889 It's going to be much then doubling. 1:08:15.889 --> 1:08:18.739 Again, you can pick--I'm sure economists have these numbers, 1:08:18.743 --> 1:08:21.263 I don't have them, you can pick whatever you want. 1:08:21.260 --> 1:08:24.580 If in order to raise most of the world from $1.00 a day to 1:08:24.582 --> 1:08:28.142 $2.00 a day you need to double their income and does the whole 1:08:28.136 --> 1:08:31.106 world rise by more than 2 times maybe 3 times, 1:08:31.109 --> 1:08:33.929 but we can pick any number that we want. 1:08:33.930 --> 1:08:37.010 I've told you two facts, that the population of the 1:08:37.009 --> 1:08:40.459 world is for sure going to increase by something like 50% 1:08:40.457 --> 1:08:42.857 before, if, and when it stabilizes. 1:08:42.859 --> 1:08:47.689 We can sort of see ballpark a 50% increase coming. 1:08:47.689 --> 1:08:51.989 Now, but this average standard of living has to at least 1:08:51.988 --> 1:08:54.128 double, and probably triple or 1:08:54.132 --> 1:08:57.792 quadruple, or again pick almost whatever number you want, 1:08:57.788 --> 1:09:02.148 so at the minimum of doubling the world's per capita income, 1:09:02.149 --> 1:09:06.909 50% more people are doubling the income means a three-- 1:09:06.908 --> 1:09:10.988 that the gross economy, well it has to triple because 1:09:10.993 --> 1:09:13.823 you have 1.5 time as many people, 1:09:13.819 --> 1:09:17.649 each earning twice as much, that's a tripling of the world 1:09:17.648 --> 1:09:18.318 economy. 1:09:18.319 --> 1:09:22.309 If you want to say that the world--that to double the income 1:09:22.310 --> 1:09:26.030 of poor people you have to triple the world economy, 1:09:26.029 --> 1:09:29.499 then that's three times more or four and half times as much. 1:09:29.500 --> 1:09:32.950 Basically we're looking at a optimistic scenario for the 1:09:32.953 --> 1:09:36.593 future where we come to a soft landing and then in order to 1:09:36.594 --> 1:09:40.494 come to a soft landing we have to have the economy of the world 1:09:40.487 --> 1:09:43.887 increase by a factor of three, by a factor of four, 1:09:43.887 --> 1:09:47.967 four and a half, five, six, somewhere in that 1:09:47.970 --> 1:09:49.970 range of numbers. 1:09:49.970 --> 1:09:53.990 Now technology--the improvement of technology allows us to grow 1:09:53.988 --> 1:09:56.208 our income with-- a somewhat less than 1:09:56.212 --> 1:09:58.102 proportionate increase in resources, 1:09:58.100 --> 1:10:01.750 and again, you can make a wild guess about how much technology 1:10:01.747 --> 1:10:05.217 will improve in the future so that we can double our income 1:10:05.217 --> 1:10:09.047 without quite doubling the drain on world's sources or the amount 1:10:09.046 --> 1:10:12.706 of pollution we put it into, or the amount of carbon dioxide 1:10:12.708 --> 1:10:13.518 we put into it. 1:10:13.520 --> 1:10:17.370 We're looking at this enormous increase in order to come to a 1:10:17.372 --> 1:10:20.412 soft landing, we're looking at this at least 1:10:20.405 --> 1:10:24.565 a tripling of the world economy, and something like a tripling 1:10:24.572 --> 1:10:28.652 of the pollution in the world, the carbon dioxide in the 1:10:28.648 --> 1:10:31.988 world, the use of resources in the world. 1:10:31.988 --> 1:10:36.478 Most people believe that we're at the limit of what the earth 1:10:36.480 --> 1:10:39.550 can cope with in terms of the economy, 1:10:39.550 --> 1:10:41.610 which is basically how much we're taking out of the earth. 1:10:41.609 --> 1:10:45.039 We're at the limit right now but with population we're not 1:10:45.042 --> 1:10:48.052 going to have a soft landing unless we triple that, 1:10:48.051 --> 1:10:50.041 at least minimum triple that. 1:10:50.038 --> 1:10:55.938 That's the significance of this population issue that can the 1:10:55.940 --> 1:11:02.040 earth cope with the tripling of the economic activity on it? 1:11:02.038 --> 1:11:04.818 I left my crystal ball home so you're going to--you are 1:11:04.815 --> 1:11:07.845 definitely going to find out the answer to that question. 1:11:07.850 --> 1:11:10.970 Okay, next time we will continue. 1:11:10.970 --> 1:11:16.000
