A recently aired PBS documentary looks at the problems and threats putting the Chesapeake Bay and its wildlife at risk.
Here's an excerpt:
In Poisoned Waters, Pulitzer Prize-winning journalist Hedrick Smith examines the growing hazards to human health and the ecosystem.
"The '70s were a lot about, 'We're the good guys; we're the environmentalists; we're going to go after the polluters,' and it's not really about that anymore," Jay Manning, director of ecology for Washington state, tells FRONTLINE. "It's about the way we all live. And unfortunately, we are all polluters. I am; you are; all of us are."
