Well, where to start? Your post is so lacking in any intelligent
thought that it's hardly worth responding to. But what the hell,
here goes. Firstly humans have been around a lot longer than 
100,000 years, so no research done there then! Secondly the 
population has never been as big as it is now so damage to the
world, which incidently is there for all bar your sort to see
would not have been in evidence before. However now it is, in
the advent of factory farming, one of the biggest causes of 
pollution in the world, how? well all the animal waste caused 
by an abnormal quantity of animals is dumped straight into 
rivers and streams destroying entire eco-systems. Thirdly and
this is where the fact that your a silly little man comes even
more to the fore, you claim the only reason that we argue 
against eating meat is because it's trendy! haha! you're clearly
using the wrong oriface at this point!!! the real reasons people
have, would range from inevitable better health, a love of animals
which judging by the way their treated clearly isn't "trendy" 
higher food yeild ( here's betting you make a comment about that
point in your response) and so forth. You then proceed to descend
into farce by saying that "poor countries" are void of vegetarians,
this is of course utter nonsense, something you seem to specialise
in,poor countries are prodominantly only beginning to add meat
to their diets, as it's a luxury, veg is cheap. If you can afford
steak and cuban cigars then clearly your the "spoiled, middle-
class, pseudo-intellectual". As for the rest of your post, it's
the pointless rants of the intellectually deprived, you dont even
bother trying to sound sensible do you?
