Glacier Melting
By: Collin Simpson
Water for life paragraph.
All humans and animals need water to survive. A large percentage of of the earth is made up of water. Most of the earths water is salt water, but it cannot be used to drink. The salt content is harmful to humans if ingested. Fresh water makes up a mere 2% of all water on earth. Of that 2% most of it is inaccessible to humans because it is in a frozen state and out of reach. Fresh water is mostly used to grow food to feed the worlds population. Smaller amounts are used for industrial process and basic household needs. As earth's population increases, the demand for fresh water also increases. A higher population needs more food, water and other basic necessities are needed for survival. Most of the fresh water is being overused and contaminate. We waste a lot of water. Water sources are being polluted by human waste and other harmful chemicals. In some places the world water pollution can cause severe illness or even death. Burning fossil fuels can have a major effect on the environment. Chemicals released into the atmosphere can lead to global warming. This can cause dangerous weather extremes such as flooding, and storm droughts which can diminish water sources. In some places global warming is causing droughts which may result in losses of animal and human life. Some countries are fighting over water sources, and the rights to those sources. According to stuart kallen “The availability and control of freshwater supplies are issues poised to define life in the twenty-first century”, if we continue to waste water, we will no longer exist.
