Better to kill them for food than for no reason at all, eh?
And do you care as much for the suffering of people?
There are other ways to imitate meat. I ate a chicken nuggets that were meatless. They taste no less than chicken nuggets. If we have a healthy way of non-artificially immitating meat, why use animals? That's so 1700's. We can survive without meat by finding other alternatives, so it's not like it's better to kill animals for food than none at all. It's not hard to understand what vegetarians are telling us. Meat eaters are just too lazy to attempt to change their diet without even trying.
The sufferings of the world is another thing, and what makes you think that animals suffering has nothing to do with human sufferings? Humans suffer for the animals, so vice versa it is important on both sides.
