For Foer, Meat Is Murder … And Worse : NPR

I do think that there are some baseline things that we should all agree on, the most important being that eating meat matters. It’s the number one cause of global warming. The U.N. and Pew Commissions have said that it is among the top two or three causes of every significant environmental problem, locally and globally: air pollution, water pollution.

So if this is the most important way that we interact with the environment, if it’s the most important way that we interact with animals, then our decisions when we go to a restaurant, what to order, when we go to a supermarket, what to buy, these decisions aren’t passing. They’re not - they can’t be casual. You know, what we choose to eat when ordering in a restaurant, what we choose to buy at a supermarket, is frankly the most important decision, or at least one of the very most important decisions we’ll make all day.
