Humanityâs challenge of the century: Conserving Earthâs freshwater systems
The challenge from here on is to avoid water wars while preemptively, cooperatively and aggressively addressing a growing global populationâs water security. It can be done, but we must do it now.
Many dryland cities like Los Angeles, Cairo and Tehran have already outstripped natural water recharge, but are expected to continue growing, resulting in a deepening arid urban water crisis.
According to NASAâs GRACE mission, 19 key freshwater basins, including several in the U.S., are being unsustainably depleted, with some near collapse; much of the water is used indiscriminately by industrial agribusiness.
