It sounds ridiculous, but a reduction in animal farts might slow climate change.

The theory is that if we ate less meat, there would be less livestock, which would mean fewer flatulent animals to release methane into the atmosphere. And it's no joke -- animal gas makes up nearly a quarter of all emissions worldwide, leading many environmentalists to believe that reducing meat consumption is a significant way for people to protect the planet.

This is all besides the fact that you're probably eating too much meat anyway. There have been a number of studies linking excessive red meat consumption to heart disease, cancer, and obesity, for instance. So by cutting down your consumption, you can better your health, and the health the health of the planet -- all in one feel swoop.
