Soon, the Avengers will return on the big screen to take the fight to Thanos and, hopefully, save the universe. Now, in the real world, two Marvel Cinematic Universe stars, Mark Ruffalo and Don Cheadle, want to save the world and make it a better place too.

To celebrate Earth Day, the two actors revealed a newly, Marvel-licensed t-shirt that showcases the Avengers and benefits environmental organizations. Ruffalo and Cheadle are both board members of 100 Is Now, a campaign of the Solutions Project which is devoted to promoting climate justice and clean energy resources around the world.
