Most of this problem comes from an American obsession with efficiency. "We are expected to get to work on time, despite the weather," he notes.
"One of our many environmental problems is that we expect convenience, and don't even know the price, environmentally."

Knaeble's concern with the overuse of salt has led him to sweep more than 270 pounds of excess deicing chemicals from his neighborhood over the past two winters. With the support of neighborhood volunteers, they are trying to prevent metro area bodies of water from becoming as salty as the sea – a problem that is largely irreversible.
