If you have water, you can think of the future
We are aware that about 71% of the earth's surface is covered with water. Almost all the water on the earth is contained in the seas and oceans, rivers, lakes, ice caps, as groundwater and in the atmosphere.
The water on the earth has been maintained for millions of years by various processes which make the water cycle.
The solid form, snow and ice, is present as ice caps at the poles of the earth, snow-covered mountains and glaciers. Liquid water is present in oceans, lakes, rivers, and even underground. The gaseous form is the water vapour present in the air around us.
The moisture in the soil indicates the presence of water underground. If we dig deeper and deeper, we would reach a level where all the space between particles of soil and gaps between rocks are filled with water
The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process. At places the groundwater is stored between layers of hard rock below the water table. This is known as an aquifer.
The upper level of water is the type of layer. This layer is called the water table. The water table varies from place to place, and it may even change at a given place.
Water drawn from under the ground gets restored by seepage of rainwater. The water table does not get affected as long as we draw as much water as is replenished by natural processes.
Increasing population
Increasing population creates demand for construction of houses, shops, offices, roads and pavements. The decreases the open areas like parks, and playgrounds.
Increasing industries
Water is used by all the industries. Almost everything that we use needs water somewhere in its production process. The number of industries is increasing continuously.
The distribution of water over the globe is quite uneven due to a number of factors.
Some places have good amount of rain and are water-rich. On the other hand, there are deserts which have scanty rainfall.
We have seen that in many places a regular supply of water is provided by a well-planned pipe system. When the civic authorities supply water through pipes not all of it may reach the destination.
Mismanagement or wastage may take place at the level of individuals also. All of us, knowingly or unknowingly, waste water while brushing teeth, shaving, bathing, washing and during many other activities. Leaking taps is another source of huge water wastage.
The rainwater can be used to recharge the groundwater. Is referred to as water harvesting.
Wherever we if we saw a tap leaking in your house, school or any other place leaking taps waste a lot of water. You must make efforts to stop the leakage.
There are a number of ways we can adopt to minimise the wastage of water.
Water-wise habits
Turn off taps while brushing
Mop the floor instead of Washing
We have seen the potted plants wilting and ultimately drying up if they did not get water even for a few days.
The green character of the planet shall be lost. This may mean the end of all life, for a world without plants shall mean no food, no oxygen, not enough rain, and innumerable other problems.
