Paul McCartney is featured in the music video for "Love Song to the Earth," a celeb-loaded track recorded in order to raise awareness for climate change.

"I'm glad to be a part of 'Love Song to the Earth,' aiming to inspire people across the world to urge their leaders to act on climate change," the former Beatle notes of the motivation behind the cut.

"We need to be fast and efficient, switching to renewable energy and eating less meat, for example.

Big decisions will be made this week, so I am doing everything I can to make sure governments sign up to an agreement, which can protect our planet. Now is the time to act. So please spread the woes and help keep our planet safe!"
