There are two good reasons for eating more fruit and vegetables in place of meat: it's better for you and it's better for the environment.

Livestock are responsible for nearly a fifth of all greenhouse emissions, from the methane produced by their guts and manure, to nitrous oxide emissions. (source: newscientist.com)
