Why is fresh water so important?

Freshwater is essential to the health of our environment and needs to be preserved and protected. Life requires water to survive it, yet our supplies are being contaminated by toxins. Water is one of nature's most important gifts to mankind. it is essential to life and a person's survival depends on drinking freshwater. Water is very important because water really controls our body, it help digest and absorb food get rid of body wastes, and serves as a natural air conditioning system. Even approximately 70% of our body is water in average. An average person should drink at least eight glasses of clean water every singe day to be in good health. If a person drank saltwater, they would eventually die because the cells in their body will dehydrate when they try to get rid of the excess salt from the water. That's why you should not waste all the fresh water when you think theres many water in the ocean. Although water is highly essential, there isn't much amounts of it. Despite the fact that 70% of the world is covered with water, more than 97% of it is unsafe water leaving about LESS than 3% of it to be fresh, clean water. Out of this amount, 70% of the freshwater is frozen in polar icecaps or glaciers. Therefore, all human and other life depend on less than 1% of the total amount of water on this planet. This water can be found on the surface of lakes, rivers, and even underground. Even though there is an extremely low amount of freshwater, it is thought to be enough to meet human needs, if it is distributed evenly around the world. Unfortunately, freshwater isn't distributed evenly around the globe with regard to either location or time of need. The fact that unsafe water is the number one killer in the whole earth because people who got no safe fresh water access must drink or use unsafe water to survive. So we must protect our fresh water because we are lucky to got so much access to fresh water.
