*Meat Free Monday

Sir Paul McCartney has urged meat eaters to consider going vegetarian one day a week. Launching the Meat Free Monday campaign, Sir Paul joined his son James and daughters, Stella and Mary, and a host of celebrities in St James's Park to launch the initiative. Stars, both vegetarian and meat eaters,- joined Macca to raise awareness of the campaign, which will help combat climate change.

The campaign was prompted by a United Nations report, which says meat production is responsible for 18% of greenhouse gas emissions. This compares with an estimated 13% from transport.
