Water Pollution

Abstract
Water is an essential part of every living thing on this plant. It is essential in such a way that every biotic function relies on it. Water is used in agriculture, consumption and fishery. For plants, it is necessary for photosynthesis, their food-making process, while for human and animals; it is necessary for digestion, blood circulation, temperature modulation and many others. It is therefore impossible for life to continue without it. Though the world is composed entirely of water, almost three-fourths of earth, only a small fraction of the entirety of it is available for consumption. According to A. du Plesuis (2017), 97% of our water is salty which is found in the sea and ocean while the remaining 3% is fresh water. This fresh water subdivides into three: glaciers, the ground water and the surface water. Glaciers and snow caps are frozen in Polar Regions and are therefore unutilized. Ground water is the fresh water that seeps into the ground after precipitation, like rain and snow, while the surface water is the one that flows through rivers and lakes. Based from the research, 99% is found to be inconsumable while the consumable 1% is found underground. These fresh water sources support our existence.
