Grist’s own Brentin Mock appeared on MSNBC’s Greenhouse this week to discuss the free market’s impact on climate change and environmental justice. He joined Greenhouse host Tony Dokoupil and Andrew Winston, a consultant to companies preparing for global shifts in the economy and environment. The three had a fascinating conversation ranging from the 50th anniversary of Selma to the question of whether ending poverty would make environmentalists of all of us. Watch the conversation here.
