I am a vegetarian and I don’t have much idea about how much meat one should have, health wise.

What is very clear is that eating meat has a massive bad influence on the environment.

Majority of crops grown are for animals not humans. These animals then become hamburgers and such. The amount of energy it takes to kill, process, transport, refrigerate etc is mind boggling. Not to mention pollution.

For this reason alone, it would make sense to eat less meat, if not quit.
