Well, there is the factor that not eating meat is unhealthy and can even cause severe problems in some people. Look at human teeth, and examine the evolution of the incisor and its purpose. The absurd vegetarian revisionism on "shredding leaves" reminds me of a similar and equally absurd hypothesis put forward by creationist "scientists" like Kent Hovind. Humans evolved to be omnivores, and probably will remain omnivores for the rest of their existence, as it is disadvantegous for a species to restrict its diet.

Anyway, cows produce far more methane than humans do, and this is largely due to their vegetarian diet. Vegetarians produce more methane than omnivores due to the effect their diet has on their digestive system. Cut back excess cows, which will, by the way, force Macdonalds and other burger chains to have to raise their prices due to the lower supply and high demand, which in turn makes them richer, the environment better, and the air a little cleaner.

Or alternatively, create regulations requiring methane collectors in every pasture. This will also create clean, waste free energy, which should also help the environment, at least as a secondary route. Once an effective method of nuclear waste disposal is found, start a large scale replacement of coal and oil power plants with nuclear ones, which will generate much more power for the world, and cut down pollution. Use the extra energy to help fuel rockets so that they are able to make faster trips to the Moon. Plant tree farms there, and collect some of the oxygen they produce into a fleet of supertankers. Then bring them down to Terra and release the oxygen, counteracting carbon dioxide the balance the air.

EDIT: Also, on the War on Terror thing, the problems from the War on Terror are the fault of humans and possibly powerful beings. Generally, if something can be stopped, its creator is one of the people who can stop it. Global warming, on the other hand, is certainly not mutually anthropogenic, and only a tiny percentage of it is caused by human activities.
