What's wrong with what we eat
The cow killing that is going on today is like a nuclear bomb. It is the new holocaust, threatening to destroy us all.
In the United States alone every year 10 billion animals are killed for food. If you lined them all up that they would reach to the moon and back five times! With that many living entities being killed there is simply no way that they can be treated ethically. Doing so also results in second highest contribution to global warming in the world (after energy production, but ahead of transportation and residences).
In this excellent presentation at the TED conference Mark Bittman reenforces much of what I talked about in the King Corn post. It is a really compelling presentation on the importance of local food (Locavore = person who only eats local food; is the new word of year), importance of eating organic food (although it isn't a cure-all) and the importance of eating less meat, less junk and more plants (eating plants is what makes us healthy).
He also talks a bit about the history of food. About how we got into the sorry state of far too much meat-eating we are in today.
Here is the video of the talk (much recommended!)
