Activist and actor Mark Ruffalo may be better known for his role as the angry green guy, but he’s been devoting his emotions and anger to the residents of Flint, Michigan in the aftermath of the Flint water crisis which has poisoned thousands.

Ruffalo has teamed up with Van Jones in order to call on FEMA to provide disaster relief to the poisoned town, despite their previous rules that they can only provide said relief in the event of a natural disaster.

Jones and Ruffalo have also assisted the town by providing water filters and helping to test individuals to see how affected they have been by the lead in their water supply.
