Description:
The Earth is easily distinguishable from other planets in our solar system by the abundance of water on its surface. Water covers approximately 70% of our world’s surface, so it would seem that finding enough water suitable for human consumption, commerce, and ecosystems is a trivial task. But, only 2.5% of the Earth’s water is fresh and of that amount, more than two-thirds is locked away in glaciers and polar ice caps and is not available to for use by society. Therefore, fresh water is actually a limited resource. Increased demand from an ever-growing population threatens to deplete precious water resources.
