Pig - Wikipedia, the free encyclopedia

Pigs are omnivores, which means that they consume both plants and small animals. Pigs will scavenge and have been known to eat any kind of food, including dead insects, worms, tree bark, rotting carcasses, excreta (including their own), garbage, and other pigs.

When you think about it, they're inherently much lower-maintenance than cows.

The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
