Lec 1 - Evolution of Sex and Reproductiv ...

"Lec 1 - Evolution of Sex and Reproductive Strategies" Global Problems of Population Growth (MCDB 150) Reproduction is not simple or easy, nor is it fair. Females often bear a larger reproductive burden of child bearing and child rearing. Reproductive strategies can be simplified into two primary strategies for males and two for females: males often either engage in sperm competition or...

Lec 2 - Sex and Violence Among the Apes

"Lec 2 - Sex and Violence Among the Apes" Global Problems of Population Growth (MCDB 150) Chimpanzee males compete for position in a dominance hierarchy; status often depends on support from other members, including females, of the group. High ranking males have much greater sexual access to females in estrus. Males control females by physical violence and intimidation. Chimpanzees also...

Lec 3 - From Ape to Human

"Lec 3 - From Ape to Human" Global Problems of Population Growth (MCDB 150) Throughout prehistoric, written, and recent history, human warfare has been commonplace. Nearly all societies engage in regular or periodic war. In many examples, human warfare has characteristics similar to chimpanzee war: an in-group fights with and kills members of the out-group. This information is not to be...

Lec 4 - When Humans Were Scarce

"Lec 4 - When Humans Were Scarce" Global Problems of Population Growth (MCDB 150) Hunter-gatherer populations were much less dense than later agriculturalists. The variety of their food supply protected them from crop failures and their sparseness reduced the spread of infectious diseases. Hunter-gatherers were healthier and worked less than early agriculturalists. Why didn't their numbers...

Lec 5 - Why Is Africa Different?

"Lec 5 - Why Is Africa Different?" Global Problems of Population Growth (MCDB 150) In addition to cultural controls acting to maximize fertility, there are important, and often competing, interests of individual families to limit fertility. Unwanted births are dealt with by infanticide in many cultures. Additionally, fertility is regularly controlled by limiting marriage within a culture....

Lec 6 - Malthusian Times

"Lec 6 - Malthusian Times" Global Problems of Population Growth (MCDB 150) In many regions, the central cultural idea is that of a lineage, a family and its line of male ancestors and descendants. The prime duty in these cultures is to keep the lineage going. Religion is small scale with the ancestors performing many of the functions of gods. Denser populations and larger political entities...

"Lec 7 - Demographic Transition in Europe; Mortality Decline" Global Problems of Population Growth (MCDB 150) European population grew only slowly during the period 1200-1700; factors include disease and wars. Human feces and rotting animal remains were not sequestered and often contaminated drinking water. Cities were so filthy that more people died in them than were born. About a third of...

"Lec 8 - Demographic Transition in Europe; Fertility Decline" Global Problems of Population Growth (MCDB 150) Prior to Malthus, population growth was seen as good for the power and wealth of a country. The rapid population growth of America was crucial in expelling England (via the Revolution) and France (via the Louisiana Purchase) from the US. But in fact, the numbers of the poor were...

Lec 9 - Demographic Transition in Europe

"Lec 9 - Demographic Transition in Europe" Global Problems of Population Growth (MCDB 150) Prior to the Demographic Transition, fertility in northwestern Europe was controlled by limiting marriage. Marriage was regulated by landowners and the churches, and was not allowed unless a man had accumulated the resources necessary to support a family. Long periods of being landless, a servant, or...

Lec 10 - Quantitative Aspects

"Lec 10 - Quantitative Aspects" Global Problems of Population Growth (MCDB 150) Census data is often politically influenced and hence inaccurate. The birthrate in developing countries is nearly twice that in developed countries. Most humans live in less developed countries, so the world birthrate is near the higher number. The world birthrate is two and a half times the death rate; we are...

"Lec 11 - Low Fertility in Developed Countries (Guest Lecture by Michael Teitelbaum)" Global Problems of Population Growth (MCDB 150) Concerns about low fertility have been present in many countries for at least 100 years. A large population was considered essential to national power. But the issue is never simply a shortage of warm bodies: overall the world population has increased...

Lec 12 - Human and Environmental Impacts

"Lec 12 - Human and Environmental Impacts" Global Problems of Population Growth (MCDB 150) Until recently, the world population has been growing faster than exponentially. Although the growth rate has slowed somewhat, there are about 80 million more people each year and about 3 billion more will be added by 2050 (a 50% increase). Population will probably increase more beyond that. Such...

Lec 13 - Fertility Attitudes and Practices

"Lec 13 - Fertility Attitudes and Practices" Global Problems of Population Growth (MCDB 150) Surveys show that most women are having more children than they would prefer to have. Further, studies show that the vast majority of women know about various forms of contraception. One World Bank study has shown that family planning programs have little impact unless they are attended by improved...

"Lec 14 - Demographic Transition in Developing Countries" Global Problems of Population Growth (MCDB 150) By 1950, in most of the underdeveloped world, mortality had fallen to about half its pre-modern rate. The birth rate, however, had remained high and, by 1950, was about twice the death rate. For the rest of the century, both rates fell dramatically and in parallel, maintaining the gap....

Lec 15- Female Disadvantage

"Lec 15- Female Disadvantage" Global Problems of Population Growth (MCDB 150) In East and South Asia there are many more boys than girls. Previously, this resulted from female infanticide, now it is sex-selective abortion. In those cultures, girls generally marry out of the family as teenagers and thus provide no benefit for the family that raised them. Bangla Desh is agriculturally very...

Lec 16 - Population in Traditional China

"Lec 16 - Population in Traditional China" Global Problems of Population Growth (MCDB 150) China's early demographic history is similar to that of Europe; population grows only slowly due to war, disease and Malthusian resource limitation. Later, introduction of American foods allowed cultivated land to expand, but population expanded even more rapidly, leading to an extremely dense, but...

Lec 17 - Population in Modern China

"Lec 17 - Population in Modern China" Global Problems of Population Growth (MCDB 150) Families lived together in traditional China and sons remained on the land; division of family land led to tiny plots and rural poverty. Because labor was so cheap, the country did not urbanize or mechanize. The Communist government started out with a pro-natal stance, but, after experiencing the famine of...

"Lec 18 - Economic Impact of Population Growth" Global Problems of Population Growth (MCDB 150) 1) Population in China: Until recently, Chinese families did not much alter their fertility depending on life events like deaths of children. However, under government prodding and eventually coercion, fertility drops drastically in China in the 1970s, but, to counteract momentum, the One-Child...

Lec 19 - Economic Motivations for Fertility

"Lec 19 - Economic Motivations for Fertility" Global Problems of Population Growth (MCDB 150) Data shows, consistently, that poor people have more children than rich people; economically speaking, children are an inferior good. Children are production goods because they do work, consumption goods because they are enjoyable, and investment goods because they support parents in old age. Jobs...

Lec 20 - Teen Sexuality and Teen Pregnancy

"Lec 20 - Teen Sexuality and Teen Pregnancy" Global Problems of Population Growth (MCDB 150) Rates of teen pregnancy in the US are quite high, in contrast to European countries which have much lower rates, especially those with liberal attitudes toward sexuality. Traditionally, puberty and marriage were simultaneous. Now, the many years spent in education leaves a long time between those...

Lec 21 - Global Demography of Abortion

"Lec 21 - Global Demography of Abortion" Global Problems of Population Growth (MCDB 150) Abortion is very common: worldwide, and in the US, there is 1 abortion for every 3.2 live births. In places where contraception is not used, abortion is used as birth control. Neither legal nor religious proscriptions have a strong effect on abortion rates. In countries where abortion is illegal,...

Lec 23 - Biology and History of Abortion

"Lec 23 - Biology and History of Abortion" Global Problems of Population Growth (MCDB 150) The idea that "life begins at conception" is not a scientific one. Since the disproof of 'spontaneous generation' (1668-1859), we have known that life only derives from life. Life arose billions of years ago and has continued since as a cycle. Assigning a beginning to a cycle (like the year) is...

Lec Last - Population and the Environment

"Lec Last - Population and the Environment" Global Problems of Population Growth (MCDB 150) World population will continue to rise until at least 2050. Environmental impact is the product of the number of people and how much of their income and technology is devoted to either consumption or conservation. So far, the balance is far at the consumption end and, globally, environmental problems...
