You may not realize what happens on land affects killer whales and salmon and the waters of Puget Sound. But, in fact, what you do at home and elsewhere can have an impact.

Consider this: As you ride to school in a vehicle, every tap of the brakes sheds a tiny bit of copper from the brake lining. The copper drops to the ground, where it's picked up by the next rainfall and eventually ends up in Puget Sound. Copper imparis the sense of smell of salmon at extraordinarily low levels, disorienting them so they're more likely to be eaten by big fish. That's bad for salmon, of course. Fewer salmon also means less fish to eat for people or killer whales, the symbol of Puget Sound.
