Hey Mr. Green,
How can I convince others that household water conservation is important?
--Matthew in New Paltz, New York
You better believe conservation is important: Waste precious water and you should be sentenced to take a cold shower with Dick Cheney. You can choose from gallons of arguments to convince people of this, but let's start with four points--pollution, wildlife, money, and stench.
When lakes, rivers, and underground aquifers contain less water (in part because more of it is irrigating lawns and dripping from faucets), pollutants become more concentrated. If we decrease water use, it could reduce the need for new dams and reservoirs that can mess up wildlife habitat.
