I just read that one about the environment. It brought up that raising cattle destroyed topsoil. They conveniently forgot to mention that it was tearing up the sod to grow wheat is what caused the dustbowl of the thirties.
Another thing that gets me is people saying that meat causes obesity. I'm sure if you eat a big mac every day it probably would. But that is not true for everyone. I have a weight problem, and I am trying to eat healthier. But I am sure it's the overindulgence in carbs that is the problem. I usually only eat meat at supper, a portion about the size of a deck of playing cards. I'm also trying to limit milk to just with cereal. That part is hard though. My brother who is 40, I'm 46, can eat meat every meal and drink milk with it and he never gains weight. It's not exercise either, he doesn't do much when he's not at work unless he's nagged into it. I'm not saying he has a healthy diet. I shudder to think what his cholesterol might be, mine is 170.
