Water is one of the most important renewable resources found on earth. It, along with food and oxygen, is one of the most basic necessities of almost all lifeforms. Our biological processes are dependent on water. Approximately 60% of our body consists of water. In our day-to-day life too, we need water for a number of households uses apart from drinking; we perform tasks like washing clothes and utensils, taking a bath and cleaning our home, etc.
We cannot imagine our life without water or with a shortage of water. Although water is a renewable resource; thereby, it cannot be completely exhausted from the earth, using too much of it or unwisely can have many nasty effects on our livelihood.
Water is perhaps the most abundant resource found on earth; nearly 71% of the surface of the earth is covered by water. There are various water bodies like the ocean, rivers, ponds, lakes, and oasis. Most of the reservoir of water, i.e., 97% is in the ocean, 2% is in glaciers and icebergs, and the remaining 1% is in the inland water bodies like rivers, ponds, etc. Also, a minute fraction, i.e., 0.001% is in the atmosphere.
Out of the total amount of water on the earth, only about 0.3% is suitable for human beings. There are various factors that render a source of water useless or even nuisance to us; e.g., water from the largest water body, i.e., the ocean is not useful for us due to the high salt content; the water is not useful for drinking, washing or any other activity. Water in the icebergs and glaciers is not practically easy to obtain for our consumption. Therefore, the small percentage of water, i.e., 0.3% may be too less for the consumption of the whole humankind; and it is important for us to use it sparingly.
The population of human beings as of current statistics is a staggering 7.8 billion (780 crores). The increasing population is adding to the water crisis. Meeting the needs of water for everyone is getting more and more difficult. Besides, due to the exploding population, apart from the direct individual uses, other and indirect uses of water like for agricultural needs, are making it even more difficult to meet everybody’s water requirements. Things like global warming cause less rainfall every year; as a result, the useful sources of water are not fully restored. Wastage of water can further add to the scarcity of water.
Some of the Important Ways of Water Conservation
Conserving water is simpler than we think. It does not involve any extra effort but to cut down our use or to use water judiciously. Here are some methods as follows:
Closing the tap as soon as the use is finished.
Closing any possible leaks in the taps, piping and storage of water like tanks.
Making alternative uses of wastewater; e.g., letting the drainage of the toilet in the farm, thus avoiding additional water for farming, and using wastewater after cleaning utensils and clothes to flush toilets.
Using dynamics of water for uses like flushing; e.g., throwing water from a height with a correct angle can help us cut down on the use of water for that purpose.
Closing the lids of water containers or tanks, especially those that are exposed to the sun; will reduce water evaporation and help us use it conservatively.
Using water sensibly and sparingly, i.e., avoiding too much water for domestic activities.
Avoiding making of water bodies like swimming pools in areas where water shortage is a big concern.
Watering the farm during the evening time, this will result in less evaporation of water.
Rainwater harvesting is collecting water from the rain. The added source of water, i.e., water harvested from the rain will be very helpful for at least a few months after the rainy season, if not for the whole year.
Planting trees in the open water bodies will keep the water from evaporation. The water can be naturally recycled for the production of fruits and vegetables. Planting trees in a huge number can reduce the carbon footprint and lower the effects of global warming, which will help timely rainfall.
1. Why is the conservation of water necessary?
Water is one of the most vital resources for almost all lifeforms on earth. Lack of water in an organism can cause dehydration and prolonged dehydration can be fatal; therefore, we need to drink water after every few hours to keep ourselves hydrated. Just like oxygen and food, we need water for our everyday needs other than drinking. About 71% of the surface of the earth is covered with water; out of the total reservoir of water on earth, only 0.3% is suitable for human consumption; therefore, although water is the most abundant natural resource found on earth and also a renewable one, water that is suitable for human consumption is scarce. Besides, the booming population is adding to the scarcity of water. Hence, water conservation is necessary.
2. What can we do to conserve water?
Water is one of the most important commodities we need on a daily basis. The growing scarcity of water, which is further intensified by the expanding population, is causing some problems for people in water scarcity-prone areas. The best way to resolve the problem is by cutting down on our daily use of water, wherever possible. Another thing we can do is repairing leakage and avoiding unwanted evaporation can help us greatly. Rainwater harvesting is a good way to increase our sources of water.
