Importance of Water
Water plays an important role in the world economy. Approximately 70% of the freshwater used by humans goes to agriculture. Fishing in salt and fresh water bodies is a major source of food for many parts of the world. Much of the long-distance trade of commodities (such as oil, natural gas, and manufactured products) is transported by boats through seas, rivers, lakes, and canals. Large quantities of water, ice, and steam are used for cooling and heating, in industry and homes. Water is an excellent solvent for a wide variety of substances both mineral and organic; as such it is widely used in industrial processes, and in cooking and washing. Water, ice and snow are also central to many sports and other forms of entertainment, such as swimming, pleasure boating, boat racing, surfing, sport fishing, diving, ice skating and skiing.
Water is one of the most important substances on earth. All plants and animals must have water to survive. If there was no water there would be no life on earth.
Plants and animals need water.
Apart from drinking it to survive, people have many other uses for water. These include:
cooking
washing their bodies
washing clothes
washing cooking and eating utensils; such as billies, saucepans, crockery and cutlery
keeping houses and communities clean
recreation; such as swimming pools
keeping plants alive in gardens and parks
Water is also essential for the healthy growth of farm crops and farm stock and is used in the manufacture of many products.
Some domestic uses of water.
It is most important that the water which people drink and use for other purposes is clean water. This means that the water must be free of germs and chemicals and be clear (not cloudy).
Water that is safe for drinking is called potable water.
Disease-causing germs and chemicals can find their way into water supplies. When this happens the water becomes polluted or contaminated and when people drink it or come in contact with it in other ways they can become very sick.
Water that is not safe to drink is said to be non-potable. Throughout history there have been many occasions when hundreds of thousands of people have died because disease-causing germs have been spread through a community by a polluted water supply.
One of the reasons this happens less frequently now is that people in many countries make sure drinking water supplies are potable. Water supplies are routinely checked for germs and chemicals which can pollute water. If the water is not safe to drink it is treated. All the action taken to make sure that drinking water is potable is called water treatment.
