How about a non-biased, concise site with over 40 well-researched pro and con arguments to the question:

Should people become vegetarian?

- In 2010, each person in the US ate an average of 57.5 pounds of beef, 46.5 pounds of pork, and 82 pounds of chicken. Vegetarians, about 3.2% of the US population, do not eat meat (including poultry and seafood). Many proponents of vegetarianism say that the meatless diet is healthier and better for the environment, and that killing animals for food is wrong. Many opponents of vegetarianism say that eating meat is natural, healthful, humane, and that people have done it for millions of years. ProCon.org’s 41st website explores the pros and cons in the debate over vegetarianism.

"Vegetarian" is too much of an identity. I am a partial vegetarian - I don't eat most meats, but sometimes I do. So I'm not a vegetarian at all, except I eat only a couple pounds of meat a year.

The average person in America probably eats two pounds of meat in three days.

If everyone reduced meat consumption to my level, one contemporary person's total diet of meat could feed meat to 100 people a year.

I see your point about Identity and Labels. In many instances, not just vegetarian, but politics in general, labels tend to do more damage then they do good.

As for the vegetarian debate, I see your point. In terms of the environmental effects of eating meat, and the world hunger implications - a reduction in eating meat provides a strong benefit without having to give up meat entirely.

However - what about the ethical issues involved with killing an animal for food when plant foods are nutritionally adequate.

Is killing animals for food wrong?

I've been a vegetarian for over 25 years (and avoid dairy products as often as possible). However, I don't have issues with traditional indigenous people hunting for meat. It's not something I could do personally, but they tended to hunt in sustainable ways, and they didn't keep mass numbers of animals in concentration camps. (Some of the slaughter house material I've seen is worse than anything ever depicted in Christian Hell.)

In some cases, the hunting techniques seem to have been humane. Some of the local Tongva used a plant that, when dropped in water, could stun fish.

In quite a few instances, the Native people felt an obligation and an indebtedness to the species they hunted and felt an affinity with them (which is why Native Americans tend to be at the vanguard of preserving buffalo and the panthers in Florida).

In our society, people tend to not know or even care where their food comes from.
