Water has an important role as homeostasis (body stability buffer). Water quality from day to day decreases. Water pollution is getting worse due to waste discharges from human activities.
About 2/3 of the earth's surface is water. Nearly 80% of the human body contains water. Can not be denied, the water is very dominating elements of life in the world.
Unfortunately, 97% of water in the world is not worth consuming because it is salty. Meanwhile, as much as 2% of fresh water is stored in snow and ice at the north and south poles. Only the remaining 1% can be consumed by living things. In reality living things lack water.
