Sting and his wife, Trudie Styler, are supporters of rain forest preservation.

“It’s always a really fun gig,” Joel told the New York Post. “They know how to hook people like me.”

The 10th annual star-studded concert is Thursday. So far, the concerts have raised $11 million to help save forests in the Amazon and elsewhere.

Sting said his foundation sets up legal infrastructure for native people to protect their own land-paying for lawyers, court fees, etc.

“We want them to legally own the land where they’ve lived for thousands of years,” he told the newspaper. “Once it’s theirs, they can do as they please with it. But we think that, because they have lived there for so long in balance with nature, they’ll look after it best.”
