Description

World population will continue to rise until at least 2050. Environmental impact is the product of the number of people and how much of their income and technology is devoted to either consumption or conservation. So far, the balance is far at the consumption end and, globally, environmental problems are increasing. Environmentalism has not come close to counteracting the footprint of a billion extra people every dozen years. The only massive success has been the decline in global fertility. People want fewer children, the contraceptive technology is available, and the cost is minimal. The only realistic possibility for ameliorating the environmental crisis might be to facilitate the continued decline of fertility.

Comment1 Mark, November 28, 2010 at 6:09 p.m.:

Consumption in developing and developed countries is the problem - not population of third world countries. The carbon footprint per capita is MUCH higher for an affluent American than a hundred people living in third world poverty. As China and India middle class grow, I do believe you will see (and are seeing) the American middle class shrink. Our EPA regulations may be the thorn in our side that conservatives will want to get rid of in order to compete with countries who have no such regulations. Overshoot and collapse? Eventually, perhaps when things heat up a bit more, the experts will be right (a perfect storm of global problems such as food and water shortages by 2030). We are living in interesting times - "survivalism" may be the fastest growing occupation for the youngest generation to get into - it could be the hobby that may save their life.
