In this article I get the impression that the vegetarians gets hammered down without a proper defence. This article talks about the circle of life, that plants are more complex then we think and almost everything contains something from an animals. The reason why people choose not to eat animals is sadly not mentioned. Maybe we shouldn't place people in box and then look for reason that box morally doesn't exist.
The vegetarians get hammered down without proper defence. True. But why? Here's the reason... The number of people living on a vegetarian diet are as few as minimum. And all the vegetarians know that it's wrong to kill animals for eating.(morally, ethically, environmentally, whatever). What we can say in defence is that you should try vegetarian diet once and you'll feel the difference yourself. What more can we say? If we say, you're going to feel better, you'll be prone to less diseases or you'll have peace and calm behaviour. Is anybody going to listen?
And I think the things mentioned here regarding the food chain. Well, LOL!
