Save the planet by having fewer kids, scientists suggest

Rising populations are a huge strain on our warming planet. A British journal suggests that we can make a difference by having smaller families. Whaddya think?

From the Chicago Tribune: "There are plenty of ways to cut your carbon footprint, whether it's driving less or buying an energy-efficient refrigerator. But the British Medical Journal, in an editorial last month, urged a more controversial one: having fewer children."

Personally, I'm only having one kid. I have my reasons.
