DiCaprio criticised over global warming crusade
Green campaigner Leonardo DiCaprio has come under fire for his attempts to raise funds to save polar bears - because he's using reams of paper to highlight the cause.
The actor, who wrote and narrated 2007 documentary 'The 11th Hour' to draw attention to global warming, recently sent out packages to members of the public in an effort to garner support for the Natural Resources Defense Council (NRDC)'s Polar Bear S.O.S. campaign.
