Former Vice President Al Gore is a trailblazer when it comes to drawing attention to what has been deemed the world's most grave environmental threat—global warming. Through his work with a variety of events and organizations, such as Live Earth, The Climate Project, and the Alliance for Climate Protection, he has been able to reach millions with his message.

Unfortunately, Gore has not yet endorsed the most effective thing that any individual can do to help—going vegetarian.

In a groundbreaking 2006 report, the United Nations (U.N.) said that raising animals for food generates almost 40 percent more greenhouse gases than all the cars, trucks, planes, and ships in the world combined. And Senior U.N. Food and Agriculture Organization official Henning Steinfeld reported that the meat industry is "one of the most significant contributors to today's most serious environmental problems."

Although the Live Earth global warming handbook identified "refusing meat" as "the single most effective thing you can do to reduce your carbon footprint," the Alliance for Climate Protection, where Gore serves as chair of the board, has has inexplicably left "going vegetarian" off of their seven-point pledge designed to identify easy steps that we can take as individuals to help end the climate crisis.

Please take just a few moments to send a polite letter to Gore and the Alliance for Climate Protection asking them to make their seven-point pledge an eight-point pledge by adding going vegetarian to the list. PETA President Ingrid Newkirk has already written to Gore and the alliance—read the letter here—asking them to alter the pledge, and now it's your chance to ask them to promote the most effective way to fight our climate crisis.
