Where is the beef? Cow flatulence doesn't cause global warming

It is safe to put a steak on the grill again. The environmentalists telling you eating meat causes global warming are lying.

The Telegraph reported:

In the past environmentalists, from Lord Stern to Sir Paul McCartney, have urged people to stop eating meat because the methane produced by cattle causes global warming.

However a new study found that cattle grazed on the grasslands of China actually reduce another greenhouse gas, nitrous oxide.
