Vegetarianism is flawed and pointless if chosen on moral grounds. Vegetarianism(as opposed to veganism, which I respect, kind of) implies that the person uses animal products but just doesn't eat meat. This can't work without people eating meat, or without the slaughter of lots of animals. So a vegetarian relies on other people eating meat to keep their animal product usage going.
Veganism is fine, but PETA, peta are evil and deserve something quick and simple.
PETA have all sort of militant tactics that they use against the weak(ever seen a peta hippy go after a women in an expensive fur coat? Ever seen one go after a biker in leathers?) and vulnerable, and claim what they do is ok because they're sticking up for things that don't even have a concept of life or sticking up for something or anything for that matter. Chickens barely register on the intelligence scale, and we, as humans, eating them, is a perfectly natural thing that we've been doing for tens of thousands if not more years.
Organic stuff is fine if you wanna spend the extra money, but it requires 4 times more land to produce the same tonnage of food, so isn't a viable option for the entire world,unless someone wants to build earth an extention.

edit: theres so much of your post I'd like to quote insanojoe, but I'll restrict myself to this
There is already surplus food in the world, quite a lot of surplus food. The reasons there is world hunger are economic and poltical, not due to a lack of food.there would be a surplus of food i.e. no world hunger.
edit2: This is a different post, so I'll let myself of with it
'course you can. I'm bigger, Im better, I've been doing it for millions of years, I like it, it tastes nice, I want to. You don't need a social or ethical arguement for eating meat, you need one for not eating meat, and currently there aren't any that I see as valid. Anthropomorphism has a lot to answer for.you simply cannot provide a social or ethical argument for eating meat
