The United States of America is segregated, and so is pollution. These words come from the so-called "father of environmental justice," Robert Bullard. As a sociologist in the 1970s, he shone a light on the fact that minority communities in Houston suffered most from pollution. Since then, he's written more than a dozen books on sustainable development, environmental racism, and climate justice. As part of "Chasing the Dream" -- our ongoing initiative about poverty, jobs, and economic opportunity in America -- Bullard spoke with Walter Isaacson in Texas. Originally aired on March 3, 2020. ........................................................................................................................
