Britons should turn vegetarian to help beat global warming, according to one of the world's top experts on climate change.Lord Stern said methane emissions from cows and pigs were putting 'enormous pressure' on the world.
The peer, who wrote an influential review of climate change in 2006, advocated a meat-free diet and called on people to think more about the effect of what they eat.
He predicted people's attitudes to eating meat would change so much with time that it would eventually become unacceptable - in the same way as drink driving.
And he 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'Meat is a wasteful use of water and creates a lot of greenhouse gases. It put enormous pressure on the world's resources. A vegetarian diet is better,' he said.
