The world population is projected to reach nine billion by 2050. Not only will these people need water to drink and bathe with also a massive amount of water must be used to grow additional food. The most rapid growth will be in developing nations, whose water supplies are already under stress.

By 2030, the number of people living under severe water stress is expected to rise to 3.9 billion, nearly half of the world population.
