In other words, we depend on water for most of our technology, comforts and conveniences, and of course for personal hygiene and to flush away our waste products. Many people think it makes no difference how much water we use or what we use it for. Actually, the way we use water is very important.

Some uses remove water from the natural cycle for longer periods than others. Worst of all, most uses actually lower the quality of the water. Water quality is everybody's business because ultimately we all draw from the same supply of water. Most Canadians live downstream from somebody else, not to mention the fact that the same basic supply of water, replenished over and over again through the hydrologic cycle, has been used millions of times over in the long history of the earth. We are now aware of limits to the reuse of water, when and where it is returned to nature diminished in quantity and quality.
