Wow, what an image that is. I know food is an incredibly emotional topic, but I wish we could agree on one thing: modern industrial farms for raising chickens, cows and pigs are an environmental disaster.
We have no way to dispose of the manure. It leeches into the ground water and is killing the Chesapeake Bay, for example. Not to mention the overuse of antibiotics, the soul-destroying cruelty to the animals and workers, the adverse health effects of meat and dairy that comes from those farms.
In my dreams, we'd require that animals be raised like they used to be: in pastures. The price of animal foods would rise, we'd eat less of it, appreciate it more, and it would be better for us. And it would extend the life of our pale blue dot.
