I have done a lot of research, and am proud and confident in my choice of being vegetarian. For me at least, I never particularly enjoyed eating meat, and I've actually been happier since I switched.
Supply and demand at it's simplest says that if enough people stop buying meat, farmers will produce less of it by breeding or purchasing fewer young animals. If only a few people are vegetarian, the effect will be small, but the more people who cut back on meat, the bigger the effect.
Actually, though, the benefits to your fellow humans are huge as well. It takes ten pounds of wheat protein to produce one pound of beef protein. Ending meat production would make a whole lot more food available for people.
Becoming vegetarian also really helps reduce your carbon footprint. 18 percent of greenhouse gas emissions come from meat production. For comparison, cars, trucks, trains, boats and planes produce only 13 percent of emissions. Not eating meat does a whole lot more than owning a Prius.
However, the health effects are a mixed bag. It really is critical to watch what you eat, because humans evolved to eat meat. Simply replacing the hamburger with french fries will really hurt you, especially if you are young. One of my friends is permanently confined to a wheel chair because of a B-12 deficiency that went unnoticed for years. I have to work hard to ensure that I get the protein and vitamins most people get from meat.
Note well: All of these effects aren't on / off. If you reduce your meat consumption by half, it will still be a huge help. What I personally recommend, at least at first, is to try not eating meat every other day. This will let you know what being vegetarian is like, and how it will affect your daily routine. Long term, cutting back on meat is a very healthy choice, without any of the risks of being fully vegetarian without a properly planned diet. Simply cutting red meat from your diet will have the biggest positive impact on your health, of all these options.
Since this is a discussion, I would also like to provide a few counter-arguments:
Many of you have said that animals eat meat, and so it's okay. Animals also rape each other (dolphins), kill each other's babies (apes), eat their own babies (Sharks), and torture other animals for amusement (house cats). We can all agree that these are not moral behavior for people.
This next bit is shamelessly ripped from Time magazine, but is convincing enough that I am sharing it here:
FIVE REASONS TO EAT MEAT:
1) It tastes good 2) It makes you feel good 3) It's a great American tradition 4) It supports the nation's farmers 5) Your parents did it
Oh, sorry...those are five reasons to smoke cigarettes.
