WHAT’S THE PROBLEM?
Our demand for water often exceeds supply. When that happens (as in Las Vegas and Atlanta now), a small imbalance can inflate into a crisis.
What do we mean by crisis? If a watershed is storing less than a year’s worth of water, groundwater is falling fast, and rain isn’t coming, it’s a crisis.
In situations like that, people MUST change their consumption behavior if they want to be able to live there in 2-3 years.
