Tell us a little about you and we'll help to plug you in..

350Brooklyn is part of a worldwide mass movement to address the climate crisis.  We stand with those around the world confronting the fires, hurricanes, droughts and poisoned air, water and land of climate change and industrial pollution on a daily basis.  We stand with the citizens, students, governments, scientists, engineers, nurses, farmers and everyone in between, fighting for solutions.  

Stand with us. We need marchers, writers, artists, researchers, fundraisers, organizers, speakers, and more.  We need your concern, your skills and abilities, your passion and commitment.  Whether it’s one hour a month or a few hours a day – whatever is right for you – we’re so excited to have you.

Filling this form will subscribe you to our newsletter as well as letting us know what you’re interested in working on so we can help you get plugged in to our organization
