Environmental justice leader Peggy Shepard points to the disproportionate impact that hazardous environmental conditions have on Black, brown and Indigenous communities and challenges us to build a truly equitable future that turns "sacrifice zones" — where community health is sacrificed for the sake of development — into "green zones" that redress the legacy of pollution and harmful policies.
