Burning carbon-based substances like oil, gas, and especially coal, produces billions of tons of extra carbon dioxide each year. Methane gas from cows and pigs and other animals on our large farms ends up in the atmosphere as well, trapping more of the sun's energy as heat. Bill Nye
I used to help my grandfather on the farm, driving tractors, raising crops and animals. I used to feed some of the baby cows and pigs, and I had to be no older than 7 or 8.

There isn't a more important issue in the world than global warming. Even the Cold War and the Bay of Pigs crisis were a notional threat. Simon Beaufoy
I didn't want to be greedy. It's a mark of bad character and I always believed that pigs go the slaughterhouse. Walter Annenberg
