The Freshwater Facts
To illustrate how important and how limited a resource freshwater is in our world, consider the following. More than 70 percent of the Earth’s surface is covered by water, but only 2.5% of this supply is considered fresh water. The rest is found in the form of salt water in the oceans. Of the fresh water that exists, most is locked up in glaciers and ice caps. Water can also be found in the form of clouds and humidity in the soil. That leaves us 3/10 of 1 percent found in the form of lakes, rivers and streams. Unfortunately, much of this small amount of freshwater is in danger of drying up through desertification or becoming so contaminated that it cannot be used for human consumption. Changing our habits of water use can help to abate this growing problem. For more information on world water consumption, you can review this government website.
