Scientific Definition Water is a chemical substance with the chemical formula H2O. A

water molecule contains one oxygen and two hydrogen atomsconnected by covalent bonds. Water is a liquid at ambientconditions, but it often co-exists on Earth with its solid state, ice,and gaseous state (water vapor or steam).

General Definition Water is very important for life. We need water to drink, to wash

our hands, to cook, to water plants and many other things. Water is the most precious natural resource on Earth. It is then a

moral imperative that water be preserved for our future survival.

Water is one of the most abundant natural resources that we have. Morethan three quarters of the earth's surface is covered with water.

We need water to grow food, keep clean, provide power, control fire, andlast but not least, we need it to stay alive.

Without water, the plants would die and people and animals would gothirsty.

Our water supply is finite, which means that we do not have an endless

supply. We only have the water that we have now. Saving water will reduce the pressure on the natural water bodies and

will help in ensuring year round supply of water and also availability ofwater for agricultural purposes.

By reducing household water use you can not only help reduce theenergy required to supply and treat public water supplies but also can

help address climate change Using water more efficiently and wisely helps maintain supplies at safe

levels, protecting human health and the environment.

1. Water crisis is a general term used to describe a situation where theavailable water within a region is less than the region's demand.

There are many other countries of the world that are severelyimpacted with regard to human health and inadequate drinking water.

2. Water is not evenly divided around the world. Some places have lotsand others have very little. Water supply is a big problem in somecountries.

3. Water pollution is the contamination of water bodies (e.g. lakes,

rivers, oceans, aquifers and groundwater). Water pollution affectsplants and organisms living in these bodies of water. In almost allcases the effect is damaging not only to individual species andpopulations, but also to the natural biological communities.

4. 884 million people lack access to safe water supplies ; approximatelyone in eight people.

5. 3.575 million people die each year from water-related disease.6. The water and sanitation crisis claims more lives through disease

than any war claims through guns.7. People living in the slums often pay 5-10 times more per liter of

water than wealthy people living in the same city.8. An American taking a five-minute shower uses more water than a

typical person in a developing country slum uses in a whole day.

1. Turn off the water when you arent using it. Running water while youbrush your teeth or shave is literally letting your water go down the drain.

2. Wash vegetables in a small bowl of water instead of under running water.This goes the same for your car. A bucket and a sponge will save gallonsof water compared to a running hose.

3. Only run the washing machine and dishwasher when you have full loads.4. Buy a low-flow toilet. Regular toilets use about 3.5 gallons of water per

flush while low-flow models use a maximum of 1.6 gallons of water.

5. Dont flush garbage down the toilet. Proper disposal is better for yourtoilet and saves water.

6. Collect rainwater. Use this water for your garden and lawn.7. Take shorter showers. An average 5 minute shower uses between 15 - 25

gallons .8. Keep cold drinking water in the fridge. Running the tap to let your water

get cold is a terrible use of fresh drinking water.
