The Elephant in the Room- Overpopulation

Some blog followers may be interested in a recent discussion-list post of the above title [Hake (2009). The abstract reads:

ABSTRACT: A recent LA Times report "Tackling the elephant in the room: overpopulation" calls attentions to a study "Reproduction and the carbon legacies of individuals" by Paul Murtaugh and Michael Schlax of Oregon State University. Their abstract reads:

"Much attention has been paid to the ways that people's home energy use, travel, food choices and other routine activities affect their emissions of carbon dioxide and, ultimately, their contributions to global warming. However, the reproductive choices of an individual are rarely incorporated into calculations of his personal impact on the environment. Here we estimate the extra emissions of fossil carbon dioxide that an average individual causes when he or she chooses to have children. The summed emissions of a person's descendants, weighted by their relatedness to him, may far exceed the lifetime emissions produced by the original parent. Under current conditions in the United States, for example, each child adds about 9441 metric tons of carbon dioxide to the carbon legacy of an average female, which is 5.7 times her lifetime emissions. A person's reproductive choices must be considered along with his day-today activities when assessing his ultimate impact on the global environment."
