Reasons Why We Should Care

Copious water supplies
1 border
Fresh water is becoming increasingly scarce

Water supply
We rely on clean water for more than just quenching our thirst. Water is so intensively used that significant portions of the world’s populations lack adequate water for drinking, sanitation, agricultural and other uses.  In fact, 1.2 billion people currently live in areas with insufficient water. Human populations are slated to rise to eight billion by 2020. As our population and pollutants increase, the shortage will only worsen. If we continue business as usual, by 2025 two-thirds of the world’s population will be without adequate water supplies, which could lead to political strife.
