World Water Crisis
The Staff of Life
Water, Earth's most precious resource, serves simultaneously as habitat, nourishment and cleanser. Brazil's Pantanal River, for example, is home to 3,500 species of plants, 400 kinds of fish, 650 bird species, 100 kinds of mammals and 80 types of reptiles. It is not only a vital waterway for man, but an essential filter for the impurities he leaves behind.
