AS SACRAMENTO legislators work on bills this week to assure the future of California’s water supply, Peter Gleick of the Pacific Institute points to the elephant in the living room. Population growth. He writes in this week’s San Francisco Chronicle:

The amount of water on Earth is fixed. We’re not losing it to space and we’re not getting more (with negligible exceptions) … But population is not fixed. It is growing, and growing rapidly in some places. As a result, the amount of water available per person (“per capita”) is declining.
