Although Water Covers Approximately Sixty-Seven Percent of the Earth's Surface

Multiple Choice

Although water covers approximately sixty-seven percent of the Earth's surface, less than three percent is fresh water. Accounting for fresh water locked in glaciers, icecaps, or otherwise inaccessible, less than a tenth of a percent of the Earth's water is available for human consumption. Pollution, population growth, and wasteful irrigation practices they are contributing to a worldwide water shortage. When the clear precious liquid becomes scarce, countries begin to assert claims on fresh water supplies. As a result, drinkable water has become a region of conflict that could eventually lead to greater hostilities between nations. In order to combat this issue many countries are adopting water conservation and security solutions. The United Nations has implemented programs to combat potential issues that could lead to violence.

B) To free water trapped in glaciers and polar ice caps.
C) To compensate for population growth which is normally not controlled
D) To satisfy rules set out by the United Nations
