Everything depends on water. We need water to drink, to wash, to swim, to grow food, and to do any number of things vital to the life of any living thing, anywhere. However, we cannot meet these needs unless we learn how to treat our water. We are misusing it. We are using too much, wasting too much, polluting too much.

Over a third of the world’s population does not have enough access to clean freshwater. People are literally dying for it. If we don’t find a way to sustain the world’s population with our water resources, clean freshwater could become more precious than the most precious of stones.
