Eat vegetables to save the earth

In the past Copenhagen climate change conference, all the leaders gathered to discuss way to reduce carbon emission. But the meeting yield no tangible result. Believe it not, saving the earth can start from you. Beside the 3R - reduce, reuse and recycle. There is another way to save the earth, by eating vegetables only.

When I was back home, Sinchew Daily run a special to promote eating vege to save the earth. The key reasons are

1) Animal farming consumes crop that could feed more people
2) Crop which used to feed animal yields less food for people
3) Cow dung release methane which cause more green house effect than carbon dioxide

Well, I think I would try to eat less meat and be more vegetarian.
