The Hulk wants you to fight for the environment. Mark Ruffalo launched the ATL100 campaign to honor clean energy heroes. Enlisting his celebrity friends, Ruffalo’s goal is to honor these impactful people for all of the amazing work they’re doing. Mark and Chris Evans shouted out local heroes by name while shooting their ‘Avengers’ movies in Atlanta. In the video, Evans says that these heroes don’t get the recognition they deserve. Ruffalo’s mission is to change that because these men and women really are Earth’s mightiest heroes, and taking care of the environment is important. Suit up, Avengers!
