In this clip from Friday's edition of "Moyers and Company," biologist and activist Sandra Steingraber discussed her quest to fight the "toxic assault" waged on U.S. children through processed food and tainted water and air.


Moyers asked Steingraber what average parents can do who are not biologists and who are unable to, say, go to jail to protest hydraulic fracturing or "fracking" as Steingraber has done.

Steingraber said that she sees it as her job to point out existing problems and direct people to the path of activism, as well as to change their thinking about the problem itself.

She pointed to the Cuban Missile Crisis, in which Americans thought they could be attacked by nuclear weapons at any time. People could respond to the crisis in two ways, to build themselves a bomb shelter or to work toward disarmament.

"I'm not going to build myself a beautifully appointed toxin-free bubble for my family," she said, "because sooner or later, my children have to grow up anyway and enter the world, right?"

She emphasized the point of community action and of people working together

"It is time now to play the 'Save the World' tympani," she said. "I don't know what instrument you hold, but you need to play it as best as you can and find yourself in the score. You don't have to play it solo, here."
