350 is the red line for human beings, the most important number on the planet. 350 the safe limit to of carbon dioxide in the world, and we need to make sure that our solutions to the climate crisis meet the 350 test.

We're planning an international campaign to unite the world around the number 350, and we need your help. The movement to spread that number needs to be beautiful, creative, and unstoppable. It needs to make sure we take the big, bold, and equitable steps needed to actually solve this crisis.

What we need most right now are on-the-ground examples for how to take the number 350 and drive it home: in art, in music, in political demonstrations, in any other way you can imagine. We don't have all the ideas and all the inspiration. We need you to act on yours.

Check out 350.org to get involved, and start planning your action today!
