Can vegetarianism save the world?

A leading climate scientist has urged people to eat less meat in order to reduce the amount of enrgy used in feeding the world. Global demand for meat has risen as the “middle” classes of many countries such as India and CHina have grown.

Raising meat requires much more energy and fuel than the equivalent amount of food energy in vegetables. Carbon emissions are also created through the transport of the meat and the creation of animal feed, not to mention the methane given off by the animals themselves!
