Document Summary
Smaller, easier divisible, and more highly productive areas may be owned and inherited by individuals. Overuse is tied to population density "a finite world can support only a finite population " A finite world can support only a finite population; therefore, population growth must eventually equal zero . Hardin: appeals to conscience won"t work, welfare state" prevents selection against many offspring. In 25 ce, asia was most populated/concentrated continent. Human population: habitat destruction a direct result of human population increases, agriculture, cities, technological advances, industry/pollution all result in destruction of. "natural" habitat, but reason our carrying capacity increases. Agriculture: food not limiting technology: advances increase k reduce death rate increase survival rate. Population density and distribution: increased density impacts the environment, but relieves pressure in less-populated areas, humans are unevenly distributed around the globe. Unpopulated areas tend to be environmentally sensitive (i. e. , deserts).
