Longtime vegetarian and animal rights campaigner Sir Paul McCartney has urged his fellow Brits to give up eating meat for one day of the week.
The former Beatle alleges United Nations officials have declared eating less meat helps to slow climate change - and MCCartney is taking advantage of the claim to promote vegetarianism and save the world.
He says, "A meat-free Monday is like going to the gym - with the advantage of protecting the planet."
