Of course April 22 is Earth Day and there were many and varied celebrations throughout the cities and states across the nation.

Of specific interest to animal agriculture, in "celebration" of Earth Day the People for the Ethical Treatment of Animals posted an article and video on its Web site with claims that meat production is the leading cause of global warming. According to PETA’s “Meat’s Not Green” video, the most effective way individuals can reduce greenhouse gas emissions — and help reduce pollution and habitat destruction as well — is by switching to a vegetarian diet.
