EDIT:
PLEASE NOTE, DISCLAIMER:
THE FOLLOWING FROM THIS PARTICULAR POSTER HAS
NOTHING TO DO WITH ANIMAL WELFARE, ANIMAL RIGHTS, OR THE IDEA THAT ANY DIET IS IN ANY WAY MORALLY SUPERIOR TO ANOTHER. THEREFORE ANY REFERENCE TO THESE THINGS HAS BEEN MADE ON A STRICTLY OFF-TOPIC BASIS AND IS NOT CONNECTED TO THE OP. ANY FUTURE REFERENCE SHOULD NOW BE ADDRESSED TO POSTERS OTHER THAN THE OP, PREFERABLY THOSE WHO ACTUALLY BROUGHT THEM UP. UNFORTUNATELY ANY ON-TOPIC COMMENTS WILL ALSO HAVE TO BE MADE TO OTHER POSTERS IF A REPLY IS DESIRED. PRIVATE MESSAGES MAY GET A RESPONSE, AT THE DISCRETION OF THE OP. IT WAS SUPPOSED THAT THE LINK TO PEAK OIL WOULD BE OBVIOUS, AND THAT NOT MENTIONING MORALITY WOULD BE ENOUGH TO INDICATE THAT THERE IS NO NEED TO ARGUE ABOUT IT. CLEARLY THIS WAS AN INCORRECT ASSUMPTION. IN THE FUTURE, THE HUMAN BEHIND THIS POST SHALL NO LONGER ASSUME THAT NON-VEGANS ARE NOT COMPLETELY OBSESSED WITH THE MORAL ISSUES SURROUNDING ANIMAL FOODS, OR WILL NOT FEEL PERSONALLY THREATENED AND LOSE ALL ABILITY COMPREHEND TEXT WHEN CONFRONTED BY THE MERE CONCEPT OF NOT CONSUMING THEM FOR ANY REASON. LESSON LEARNED.
The 'we're designed to eat meat, so we need it' argument is flawed. This is partly cut and pasted from my post in another thread:
We're designed to
be able to eat meat (and raw meat only - carcinogens in cooked meat may be partly responsible our species' and meat-eating Western society's cancer levels, hence vegetarians in the West get 3 times less cancer and live 7 years longer than their meat-eating neighbours), among many other things. Humans have the ability to obtain every one of our essential nutrients from non-animal sources, provided the soil we live off of contains the right mineral balance (e.g. enough
cobalt to make vitamin B12), as it used to. Find me
just one nutrient that humans can obtain only through eating animal products, and I will concede that we are designed to need meat. So far the desperate meat and dairy and recently, fish industries, despite their best efforts, have failed to validly do so, so I doubt anyone here can either.
It's like saying we're designed to need nuts. We can live with no deficiencies at all on a diet without that particular food group, even though we're designed to be able to safely get nutrients from them if we do include them.
I also find it funny that people who are appalled by the idea of GM crops eat farmed animals, as these were all genetically modified in a far more haphazard way than the DNA engineering carried out now. Modern 'cows' and 'pigs' that have had their wild instincts largely bred out of them by human selection, look much more different to their ancestors than GM carrots look to non-GM carrots. How can we know how different their nutritional content might be to that which our ancestors consumed, even if uncooked?
Here's one helpful example of the many webpages addressing important things for vegetarians and vegans to know.

I recommend as much research about nutrition as possible, especially for people who aren't vegetarians now but think they're likely to be forced to be in the future. Personally, I'm going to apply for one of the few courses, commissioned by the National Health Service, that make possible registration with the Health Professions Council as as a qualified Dietician. It's six years of continuous study, so I shouldn't forget a word by the time the knowledge becomes vital.
Finally, relax. This article shows that it's possible for people outside of civilisation to live long, happy lives as vegans. Longer than the Western average, actually:

The few thousand Brok-pa Aryans have over 5,000 years lived in these hostile terrain at 15,000 ft altitude, subsisting on a vegan diet.
Music and dance are a way of life for them. Both men and women wear colourful costume, decorating their hair with flowers, and are full of joi de vivre. They live in harmony with nature, and are cheerful and stress-free despite living in small rock shelters. They trek long distances.
Almond, apricot and walnut form part of the diet along with endless cups of black tea fortified with barley flour.
The weather in September is pleasantly cold, though temperatures in January can plummet to -20 degrees Celsius. There are an unusually large number of Aryans above 70 years. Many are active even at 90.
