From the Bronx to Belfast to Los Angeles, The Promised Land: Earth Day Special with host Majora Carter navigates the intersection of environmental, social, and health issues. Learn why the new Yankee Stadium has raised questions about the use of community resources; how a £30 million project will bring hope to Northern Ireland's abandoned middle ground; and why an L.A. organization called TreePeople wants the infrastructure of our cities to look more like the infrastructure of our forests. And listen as longtime environmental activist Robert Redford weighs in on where he thinks we're headed.
