Britain’s Climate change Chief, Lord Stern, urged Britons to give up meat to save the planet. He suggested that Britons should turn vegetarian to help beat global warming, as methane emissions from cows and pigs were putting ‘enormous pressure’ on the world. He predicted that eschewing meat would change so much with time that it would eventually become unacceptable - in the same way as drink driving. Stern also forecast the price of meat and other foods that generate a lot of greenhouse gases could rise after December’s pivotal climate change conference. So do you think going veggie can save the planet earth?
