No offense, but saying animals are here for us is just mean
I think killing animals is completely unnecessary, as countless people prove every day as they live a vegetarian life style
Before I became a vegetarian, i made sure the meat I ate was from an organic farm (which isn't hard to find, you know)
Now that I no longer eat meat, I still only eat dairy and eggs that are organic, and when I'm older, will buy local on top of the organic part.
It's one thing to eat meat, but to raise an animal for that purpose? Especially in the conditions most of the animals live through (80%), it's just disgusting!
I think if you're going to eat meat, you should at least go hunt it yourself
