"Water, water everywhere,but not a drop to drink." You must have heard this phrase many times in your life.it means that although there is water all around us, in Earth's oceans, seas, lakes, rivers, etc. Most of it is not drinkable water! The oceans cover up more than 70 percent of all of the Earth's surface. So save water is vital to our planet. We must all do our part in conserving water because it is a finite resource. Water should be used only for necessary work and should be saved for activities that require large quantities of water.
