Alex Steffen, editor and co-founder of WorldChanging.com, encourages college to take charge in the green movement.

Alex Steffen thinks we're doing almost everything wrong when it comes to sustainability.

The editor and cofounder of WorldChanging.com suggests we need to think big to handle a big problem. Driving less and eating less beef are important choices, but they only represent a fraction of what we can do to enact major changes to the system.

Endicott, N.Y., is now a "toxic plume" after the old IBM plant spilled toxic chemicals into the ground in the 1970s.

Mark Bacon of Endicott lives at Ground Zero.

He lives across the street from IBM's former plant on North Street in Endicott, N.Y., a facility that during its manufacturing processes spilled toxic chemicals into the ground in the 1970s.

Years later, the vapors rising from the trichloroethylene (TCE) polluted grounds are allegedly making residents of the town sick.

It's also partly to blame for the town's economic decline.
