Water is Essential for All Life

Water for Life
All humans and animals need water to survive. A large percentage of the earth is water. Most of earth’s water is saltwater. However saltwater can not be used for drinking because it contains too much salt and drinking saltwater is very dangerous. There is actually a very small percentage of freshwater on Earth. Only about 2% and of that 2% most of the water is inaccessible because it is frozen or out of our reach. Freshwater is mostly used to grow crops to feed the worlds population. Smaller amounts are used for household purposes and industrial processes. As the Earths population increases, the demand for freshwater also increases. More people means more basic materials like food. Earths water supply is running thin. Earth does not have a never ending supply of water. Many of our main water sources are drying up. We are also wasting water because of our inefficient drain systems. Our water sources are also being polluted by human feces and harmful chemicals. In some places like third world countries the pollution is so severe that it causes death. The continued practice of burning fossil fuels is having a harmful effect on the environment. Climate changes is causing extreme flooding and droughts that are threatening water sources. Extreme droughts are leading to a large loss of animals and humans. An increasing demand for freshwater has lead to conflict between countries. Water is the foundation of almost all life on Earth. Without it, life as we know it would cease to exist. The availability and control of freshwater supplies are issues poised to define life in the twenty-first century.
