Washington, Apr 29 : Legendary singer Sir Paul McCartney has written an open letter to actress Pamela Anderson urging her to promote vegetarianism.

The ex-Beatle, who himself is a strong animal rights advocator, has appealed to the Baywatch star to help, after both became involved in a campaign to help the plight of seals.

Anderson had urged to ban the slaughter of baby seals in her native Canada, while Macca urged the European Parliament to implement a ban on the sale of all seal products.

He''s written a two-page letter hoping that vegetarian Anderson will help him promote the cause, reports Contactmusic.

McCartney writes, "Dear Pamela. We are sending this letter because both of us share a concern for our planet''s welfare and hope you will find the following information of interest. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) stated that ''changes in lifestyle and behaviour patterns can contribute to climate change mitigation across all sectors.''

"A significant reduction in emissions can be brought about through changes in diet. The single most effective act is to become vegetarian or reduce meat consumption.

"Unfortunately, with higher incomes, societies are turning to greater consumption of animal protein, which reduces the availability of food grains for direct consumption by impoverished human beings.

"We are, therefore, writing this letter not because vegetarianism is a fad or an emotional issue but because it is a very attractive option for reducing emissions of greenhouse gases and stabilising the earth''s climate and ensuring food security." (ANI)
