One of the world’s most innovative grassroots environmental groups, 350.org, is helping build a movement to unite the world around solutions to the climate crisis. This video makes clear how high the stakes are and explains why 350 is the most important number in the world.

In preparation for what it anticipates will be a major day of international actions on October 10, 350.org is giving out microgrants of $1000 to local climate action projects in the planet’s eight major regions. These funds have been made possible thanks to a partnership with the Global Greengrants Fund, which is the world’s leader in providing small grants to grassroots environmental groups around the world. Anyone can submit a project until August 7.  A public vote decides the winners. The only real admissions criteria, beyond the imperative of combating climate change, is that the project have some sort of milestone on 10/10/10—the Global Work Party: "A Day to Celebrate Climate Solutions"—either a kick-off event, the culmination of an initiative, or some other significant moment.

Possible projects include local renewable energy initiatives, community gardens, sustainable transportation measures, political lobbying projects, the creation of green media and much, much more.
