As global population increases, so does water usage and stress on available clean supplies.
Inequitable access to water and recourses based on geography and wealth is a leading problem now
and will continue to be in the future.

The US Census Bureau estimates that the resident population of the United States is more than 314 million (September 2012):
One birth every 8 seconds, One death every 14 seconds,
One international migrant (net) every 46 seconds.
A net gain of one person every 13 seconds.
