Kathy Freston has an article on AlterNet about switching to a vegetarian diet to help fight global warming. This isn't the first article AlterNet's had on the subject, and I'm happy that people are starting to realize that eating meat is detrimental to the environment. And even though I'll always promote a vegan diet (not just for the earth either - but for the animals!), you don't have to stop eating meat altogether to help the environment. You can just eat less meat.
Eating Vegetarian is Taking Global Warming Personally
