I found a Canadian environmental site, that had good information about what you can do for the environment.
"Individuals can do something about conserving and using water wisely!" -was a list that everyone should read and just do the things that everyone can do in their own home.
Here are a few of the "DOs and DON'Ts":
*Keep a bottle of drinking water in your refrigerator instead of running your tap until the water gets cool each time you want some water. Do not forget to rinse the container and renew the water every two to three days.
*When brushing your teeth, turn the water off while you are actually brushing instead of running it continuously. Then use the tap again for rinsing and use short bursts of water for cleaning your brush. (This saves about 80% of the water normally used.)
*Take short showers – turn off the water while you are soaping and shampooing and then rinse off quickly.
