Waste, from food to plastics, not only affects climate change but also affects people's lives in ways that we don't always consider. Saumya Roy brings these issues to life in her book "Castaway Mountain," which chronicles a community living in Mumbai's vast Deonar garbage mountain. In this podcast, Roy and Carnegie Council Senior Fellows Tatiana Serafin and Nikolas Gvosdev discuss how Mumbai's forgotten community reflects the massive problem of waste around the world.
