People will need to turn vegetarian if the world is to conquer climate change, according to a leading authority on global warming.
In an interview with The Times, Lord Stern of Brentford said: “Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the world’s resources. A vegetarian diet is better.”
Direct emissions of methane from cows and pigs is a significant source of greenhouse gases. Methane is 23 times more powerful than carbon dioxide as a global warming gas.
Lord Stern, the author of the influential 2006 Stern Review on the cost of tackling global warming, said that a successful deal at the Climate Change Conference in Copenhagen in December would lead to soaring costs for meat and other foods that generate large quantities of greenhouse gases.
