Check out FOX explaining why cutting down on your meat consumption is the way to in preserving our planet. You don't have to become a vegan (although that would nice)--just be mindful of the extent to which you consume animals. I always like to say only have animal in one meal a day.
Here are some goodies from the article:
"Give up meat for one day [a week] initially, and decrease it from there," Dr. Rajendra Pachauri [the head of the U.N.'s Intergovernmental Panel on Climate Change] told Britain's Observer newspaper in comments published Sunday.
Pachauri reasons that because raising, feeding, slaughtering and shipping livestock produces much more greenhouse gas than does growing plants, a decrease in the number of livestock worldwide would do a lot to offset the threat of global warming.
"In terms of immediacy of action and the feasibility of bringing about reductions in a short period of time, it clearly is the most attractive opportunity," he told the Observer.
A U.N. study in 2006 found that 18 percent of greenhouse-gas emissions came from the livestock industry, chiefly in the form of methane burped up and otherwise emitted by cattle, sheep and pigs.
Additionally, as meat consumption grows as developing countries get richer, more and more forests are cut down for pasture, resulting in fewer trees to replace carbon dioxide with oxygen.
