To mark the 50th Earth Day, we’re re-airing a piece from 2017.

In his proposed 2021 fiscal year budget, Trump has asked Congress for the fourth year in a row to slash funding for the Environmental Protection Agency, essentially stripping away the last remaining programs aimed at curbing climate change. Earlier this month, as Americans were transfixed by the pandemic, EPA director (and former coal lobbyist) Andrew Wheeler announced that coal- and oil-fired power plants would no longer need to comply with regulations designed to reduce mercury and other toxic pollutants. 

But flash back to the late 1960s and it's a very different story. The environment was a bipartisan issue, and a Republican president created the EPA in 1970 in response to public pressure. So how did we get here? How did the environment go from universal concern to political battleground — with the EPA caught in the crossfire? 

With the help of Richard Andrews, professor emeritus of environmental policy at UNC Chapel Hill, and William Ruckelshaus, EPA administrator under presidents Richard Nixon and Ronald Reagan, Brooke considers the tumultuous history of the EPA, its evolving relationship with the public, and its uncertain future.
