Water, Water Everywh | |
| Ironically, the world’s most precious resource is also one of its most plentiful. More than three-quarters of the world is literally covered in water. Yet, only 1 percent of the world’s water supply is fit to drink. Ninety-seven percent is salt water, and 2 percent is frozen in glaciers or polar ice caps. | ||
