Save the Planet: Have Fewer Kids
For people who are looking for ways to reduce their "carbon footprint," here's one radical idea that could have a big long-term impact, some scientists say: Have fewer kids.
A study by statisticians at Oregon State University concluded that in the United States, the carbon legacy and greenhouse gas impact of an extra child is almost 20 times more important than some of the other environment-friendly practices people might employ during their entire lives - things like driving a high mileage car, recycling, or using energy-efficient appliances and light bulbs.
"In discussions about climate change, we tend to focus on the carbon emissions of an individual over his or her lifetime," said study team member Paul Murtaugh. "Those are important issues and it's essential that they should be considered. But an added challenge facing us is continuing population growth and increasing global consumption of resources."
