The Distribution and Availability of Fresh Water on Earth
H2O is one of the most resources on our planet. It is composed of two hydrogen atoms and one oxygen atom. Together they form one of the most vital compound elements on the planet. In the 21st century the world is realizing just how important water actually is. Countries dispute over who controls the water and how the water is used. Everything that humans do every day needs water to either be put into their body or into a machine to accomplish a job. For so long America has been portrayed as the country with the best quality and ability to produce a large quantity of water. The U.S. may have an edge over some third world countries but according to some environmentalists, we may not have the quality of water that we think we have and neither does the rest of the world.
According to the United States Geological Survey’s (USGS) Water Science School the three spheres on the picture on the left represents all of the water on and above the earth. The largest sphere is all the water on, in, and above the earth at 860 miles in diameter. The second smaller sphere is all the freshwater at only 169.5 miles in diameter. The third and barely visible sphere at 34.9 miles in diameter is fresh water in rivers and lakes. The last sphere is the most commonly used form of water humans consume on a daily basis. Although water covers 71% of the earth’s surface, as seen above it is not quite as much as perceived.
People tend to not consider where their water comes from or how it is purified. It is natural not to question where the water is coming from when showering or performing other regular bodily cleaning procedures. Humans are creatures of habit and as such do not ask questions such as: “Where did this water come from?” “How clean is the water?” or “Have you tested the pH levels regularly.” Those questions are not something that people find themselves asking on...
