Human Populations I. Population growth A. For most of human history, humans have not been very numerous B. It took all of human history to reach 1 billion C. Human population tripled during the twentieth century. II. Limits to growth A. Thomas Malthus (1798): human populations tend to increase exponentially while food is plentiful 1. Humans outstrip food supply; population collapses 2. Human population only stabilized by positive checks. 3. Humans are too lazy and immoral to voluntarily regulate birth rates. 4. Limits to growth B. Karl Marx: population growth is a symptom rather than a root cause of poverty and social problems 1. Real causes are exploitation and oppression 2. The way to slow population growth and alleviate many social problems is through social justice. C. Malthus and Marx today 1. Neo-Malthusians - we are approaching, or have surpassed, earth’s carrying capacity - We should make over-population issues our first priority 2. Neo-Marxists - eliminating oppression & poverty through social justice is the solution
