Last semester at school some wacko environmentalist group decided to let everyone know that eating meat is destroying the planet. How did they do this? They printed pamphlets and put them on every single car and bike on our campus of 40,000 students. I only drove my car a couple times a week and I only rode my bike once the entire year so I never took the thing off of my bike. They stayed on bikes and cars for a couple of weeks. By time someone finally took them off of everything they had started blowing around campus.
So the crazies were perfectly fine with the dozens of trees they "killed" and the litter they created, as long as we stopped eating meat.
