Availability of water
Water is the most widely occurring substance on this planet. Globally distributed by the hydrological cycle, driven by the energy cycle, the circulation of water powers most of the other natural cycles and conditions the weather and climate. Water has shaped the earth’s evolution and continues to fashion its programmes. This is the water precipitated from the atmosphere on to land, where it may be stored in liquid or solid form, and can move laterally and vertically and between one phase and another phase by evaporation , condensation , freezing and thawing on the land surface. This water can travel at widely differing velocities usually by predictable pathway’s which can slowly change with time. 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. However, most of this water is not fit for human consumption.

How much water do we use?


Introduction: It is common knowledge that water is important on our Earth and without water, life as we know it would cease to exist. While Earth has an abundant reservoir of water, covering three-fourths of its surface, Freshwater is a mere 2.6% of the total water. Water is said to be a renewable resource but the rate at which humans and animals are using water, fresh water might be a scarce resource in the recent future. Our body is also made up of 70% water and we use water for a number of reasons from cooking to cleaning and of course drinking it. A lot of experts predict that the next World War will be fought over water.

How Much Water Do We Use?

  • Water makes up a majority of your body weight and is involved in many important functions, including:
  • flushing out waste from your body
  • regulating body temperature
  • helping your brain function
  • Water is precious, fundamental and the most essential substance required for the existence of life on earth.
  • Water is found naturally, abundantly on our planet earth.
  • About two-thirds of the total earth’s surface is covered with water.
  • Water is a transparent, odorless and tasteless inorganic molecule composed of hydrogen and oxygen.

Uses of Water

We all use water for different purposes, which includes everyday household uses, including:

  • Drinking
  • Cooking
  • Cleaning
  • Washing
  • Bathing

for other domestic, irrigating, cultivating the crops and industrial requirements. 

Thus, water is required for many activities, therefore it is an essential element required for the continuity of life on the planet.
