ABC 'News' has a nice photo feature on famous vegetarians.

The first shot is of Heather Mills, Paul McCartney's estranged wife, who believes strongly in being vegan. In March she helped Viva! raid a UK pig factory farm to raise awareness of animal cruelty. And in November, Mills made headlines after she launched Viva's HOT! campaign in London's Hyde Park to raise awareness of the connection between eating meat and climate change.

Using figures from a report on global warming by United Nations Food & Agriculture Organization, Viva! argues that livestock are the second biggest cause of greenhouse gases – 18% compared to 13.5% from all the world's different modes of transport combined – and the principal cause of rainforest clearance with 70% of cleared Amazon lands used for grazing and 30% used to grow feed crops for animals.

Other vegetarian celebrities featured include, actor Joaquin Phoenix, Idol star Carrie Underwood, actress Alicia Silverstone, pop icon Prince, Natalie Portman who cites her love for animals as her reason for being vegetarian (she also doesn't wear leather), "Spiderman" Tobey Maguire,  "Tonight Show" band leader Kevin Eubanks, Lisa Simpson, and Kristen Bell and Milo Ventimiglia who star in the television show, Heroes.

Bell says she has been meatless since she was 11 years old because she couldn't disassociate a hamburger from her dog.
