Conversations with interesting people about the stuff they love.

"What We Need Now," the monthly podcast by Greenpeace USA, is where you can learn about the work grassroots leaders are doing from the leaders themselves.

Each episode, the hosts explore a different topic related to the intersections of climate, racial and environmental justice, and our movement for a green and peaceful future, and pass the mic to local leaders who are fighting for the world we want to see. 

Greenpeace is an independent, campaigning organization which uses non-violent, creative confrontation to expose global environmental problems, and to force the solutions which are essential to a green and peaceful future.
