Abaddon,
Population pressure is no sociological artifact. I find it interesting that you seem to have interpreted my posts to mean that I am concerned with the effects of the population explosion on the food supply.
Exponential population growth does indeed threaten more famine, not due to lack of food resources, but due to greed. Nevertheless, the ill effects of the population explosion is not limited to the food supply. Plants and animals are endangered and threatened with extinction due to the elimination of their natural habitat caused by the uncontrolled expansion of human population. The need for energy and water is also intensified by the population explosion, and foolish politicians in this country respond to that need with a push to expand the use of nuclear power, resulting in additional pollution issues. Overpopulation has also resulted in dangerous levels of pollution of our air, water, and land.
To assert that population pressure is merely a social artifact ignores a serious problem and is analogous to burying one's head in the sand.
