Water Conservation is more important than you think.
Pollution has also taken a toll on the water supply. Lots of pollution makes lots of acid rain. Acid rain isn't the cleanest water to drink, (since it has pollutants), but people who rely on rainwater most likely don't have the materials needed to filter their water.
Start Conserving Water at Home!
-Only run the washer and dishwasher when they're completely full
-Don't keep the water running when you brush your teeth
-Shorten your showers
-Water your lawn only when needed
-When washing dishes by hand, fill the sink first, then wash them all instead of letting the water run.
-Use a broom instead of a hose to clean driveways and sidewalks.
There are many other ways to save water, but putting some of these methods into practice can save you many gallons of water, and allow others to have more water available to them.
