I feel guilty. I'm not completely vegetarian, but I don't eat much meat, and when I do, I feel bad. I grew up on a farm. And for a long time, I believed what I called the "circle of life." Animals were made to be eaten, we eat them, it's all a big happy circle. Some years ago, my beliefs changed to what I call "all life is precious." I think animals have value. Not as much as humans, but some value, and I'm morally obligated not to harm or kill them if I can help it. Which I can, in my socioeconomic environment. I don't really have a good logical defense for it. It's more of a feeling. But meh. I think the masses are largely ethical egoists. I think we'll get to the point where we can grow equally good meat in a lab, cheaper. And within thirty years, the majority people in the first-world will believe eating meat is unethical, once it's convenient for them. I don't think it will be a bad thing; though it will worsen the diversity problem.
