Water is essential to human and organisms to live “Drinking water, “2008). Water covers most of the world and makes up more of the world than land. Water comes from different sources. Water may surround us but there are still shortages. Water allows us to live but it could be harmful to our bodies when polluted. Humans and natural disasters can cause damage to the water supply It is important to conserve water whenever possible (“Drinking Water, “2008).
Oceans make up two-thirds of the Earth (“Drinking Water,”2008). It is made up of saltwater. This water is not useable for humans to drink or use for food. Even though it is not a water source for organisms or humans to drink, it has it own importance in the world. It contains organism sources for food, like fish, lobsters, squid, and clams to name a few (“Why Oceans,” 1998). The ocean helps with the carbon dioxide in the atmosphere, which helps lower climate change. Climate change is a continuing problem humans are dealing with today. Humans dispose different substances like chemical weapons, and radioactive material into the ocean that is banned on land. River pollutants are washed into the ocean, to help provide cleaner rivers (“Why Oceans,” 1998).
The world is only made up of 3% fresh water (“Why Ocean,” 1998.) Almost two-third of fresh water is not even liquid format. It is trapped in glaciers and ice caps. Ground and surface water consist of other fresh water. Ground water provides for almost half of the world’s drinking water. It is also important for our agriculture, industrial and environment uses. Surface water consists of rivers, swamps and lakes. It provides for a small factor of drinking water but it is still important (“Drinking Water, “1998).
Water is recyclable (“Drinking Water,”1998.) The water that is here today is the same water that was here million of years ago. Water goes through a cycle
