Beef especially is very taxing on the environment. It takes a lot of energy to get to beef and there is methane from cow manure causing greenhouse effects. I enjoy a nice steak but suggesting there is no negative side effect to the environment....

That's where the comparision breaks down. The point is, the more beef people eat, the more cows there will be, not less. Same as the more paper people use, the more trees there will be, not less. Of course the impact of cows and trees on the environment is different and besides the point.
