We already know that Water is the most important resource on the planet. It is the essence of all life on earth. And yet if you ever see a river or lake around your city, it would be evident to you that we are facing a very serious problem of Water pollution. Let us educate ourselves about water and water pollution.
Water and Water Cycle
Two-thirds of the Earths surface is covered by water, seventy-six perfect of your body is made up of water. As you already know water is everywhere and all around. However, we have a fixed amount of water on earth. It just changes its states and goes through a cyclic order, known as the Water Cycle.
As shown in the image above, the water cycle is a natural process that is continuous in nature. It is the pattern in which the water from oceans, seas, lakes etc gets evaporated and turns to vapour. After which it goes through the process of condensation, and finally precipitation when it falls back to earth as rain or snow.
Water pollution is the contamination of water bodies (like oceans, seas, lakes, rivers, aquifers and groundwater) usually caused due to human activities. Water pollution is any change in the physical, chemical or biological properties of water that will have a detrimental consequence o any living organism.
Drinking water, also called Potable Water, is the water that is considered safe enough for human and animal consumption. This is water that is generally used for drinking, cooking, washing, crop irrigation etc. These days chemicals, bacteria and other pollutants are even affecting our drinking water.
