Paul Erlich is a notable population biologist and the author of many scientific papers. In this paper he argues that starvation and ecological crises are inevitable consequences of a population explosion. He says that we are beginning to realize that food production won’t  be able to keep up with that rise.

According to the article, around two-thirds of the worlds population lives in under developed countries that have rapidly growing population, and most of those people are hungry. It is different in over developed countries. In over developed countries most people are adequately nourished. In fact, over developed countries consume majority of the worlds resources.

Paul Erlich considers the growth of population bad, and asserts that it will cause major problems in the future.
