This Green Life
There are strong environmental reasons for becoming vegetarian (some of which in my opinion would make sense to the staunchest carnivore), and this month’s This Green Life from the National Resources Defense Council sums out some of them. Whatever one’s reasons for avoiding the consumption of meat,the environmental facts may be the hardest to argue against.
For further reading, I recommend John Robbins’ The Food Revolution. The above linked article also has links to Facts about Pollution from Livestock Farms and The Issues: Factory Farming.
