Methane is a potent greenhouse gas, 20 times more powerful than carbon dioxide at trapping heat. New Zealand scientists have developed a vaccine to cut down on livestock flatulence, which should help farmers avoid a proposed “flatulence tax” on the methane their livestock produces.

"Mother Nature's Son," Sir Paul McCartney, recently expressed his disappointment with environmental NGOs for not putting greater emphasis on reducing meat consumption -- along with driving less and replacing standard light bulbs with CFLs -- as ways to fight climate change.

The Great American Meatout encourages you to give up meat for a day (or more). Here's a look at some of the environmental reasons why that's a good idea.

But livestock emissions are no joke.
