What is a root cause for population?

Overpopulation is the elephant in the living room that no one's talking about. It's one of the biggest global threats. I think people avoid the subject because it involves birth control education, including abortion. The Bush administration has instituted the Global Gag Rule, which restricts foreign non-governmental organizations that receive money from the USAID's family planning program from using their OWN non-U.S. money to -provide safe abortion services -impart any information about abortion -engage in public information services about abortion Here is a good site with info: http://www.populationconnection.org
