The corralling of animals for slaughter is bad for the environment and the physical and moral health of all involved. Its terribly needless suffering, though I realize most people, and most of my friends, need their bacon and burgers.
I wish everyone who thinks all vegetarians are PETA nuts would try giving up meat for a year and see how they feel (not just physically but also about the idea of tearing flesh off of bone and swallowing it, of ten still bloody).
Yuck.
