Document Summary
What happens when there is not enough land: these new u. s. immigrants encountered a number of problems, one of the first problems was that native americans occupied the land they wanted to farm, the solution adopted was very direct and brutal. Malthus" theory: malthus"s theory of population proposed natural limiting factors which put an upper bound on the number of people. Natural resources grow arithmetically, if they grow at all. Opposite side of the spectrum is work by michael kremer. His research shows world population growth fosters progress. You need a critical mass of people for advanced societies to develop. societies with high pulations are the most dynamic and most productive. Key formula: population density measures extent of overcrowding. 5 million / 23 miles 217,000 people per sq. mile. Example: manhattan (key part of nyc) is 23 square miles. During the night 1. 5 million people live in manhattan. During the day roughly 5 million people live, work, shop and visit in.
