There plenty of reasons not to eat meat these days. I can think of so many off the top of my head.
Instead of me typing for 1/2 an hour, watch a fun cartoon:

There is also some inaccuracy in these films. It's even worse. Calves raised for veal are kept in tight wooden boxes so they don't lick iron bars or turn around to drink their own urine to get iron in their body. They can't even lay down. FYI iron deficiency hurts like a bitch. This is all to keep their meat as pink as possible. They are slaughtered when they reach 6 months of age. Most of them don't survive but the profit from the meat is so high it doesn't matter. Screwed up, no?
Also in egg laying farms, the males are grided up alive and are fed to the egg laying hens to cut back on losses. These hens are packed so tightly into a single cage that they can't move and they soon grow deformities where the skin on their feet will grow around the metal mesh and their talons will grow so long that they become tangled in the mess aswell.
That's only a small part. Don't ignore this. The antibiotics and growth hormone are absorbed into your bodies and the pollution caused by excrements is incredible. Why do you think we have had so many avian flu epidemics in the past? Not hard to see why. Get informed people.
