What did you want to be when you were growing up?
Exactly what I'm doing now.
How did you get started in your field of work?
After I finished graduate school at Duke, I landed a job with a small natural resources consulting company in California. My first assignment was to help write a handbook for communities across the country to use in designing water conservation programs. I worked with a civil engineer who knew all about urban water and wastewater systems. It was perfect. Three years later, I joined the Worldwatch Institute, where I happily occupied the global water niche. It all unfolded from there.
What inspires you to dedicate your life to freshwater?
I love nature—and water is the source of it all. I care about the mussels and fish and frogs that depend on water. The extinction of life pains me. I just want to do my part to be sure we humans conserve water and share it with all of life.
What’s a normal day like for you?
Hours of reading, thinking, writing. Quite often a plane ride to give a talk somewhere. Exercise—a walk or run, maybe some tennis. Depending on the season, some work in the vegetable garden or carrying in wood. Then back to reading, thinking, and writing.
Do you have a hero?
Marjorie Spock. She's not well known. She took the federal government to court in 1958 to stop the aerial spraying of DDT across Long Island. She became a good friend of Rachel Carson's. I met Marjorie when I was researching that spraying. She was 101 and sharp as a tack. She was still holding weekly philosophy discussion groups at her home in Maine. She had a rare blend of wisdom and humility. I corresponded with her occasionally until she died in 2008 at 103. Marjorie Spock is but a footnote of history but she helped change the world.
If you could have people do one thing to help save freshwater, what would it be?
Landscape with native plants, grasses and shrubs, and avoid planting thirsty lawns in dry places.
More About Freshwater
Flash floods following mountain fires pose increasing threats to drinking water supplies—and add impetus for forest thinning and watershed rehabilitation in the western United States.
Every winter an amazing sandhill cranes migration takes place in the West. The birds journey long distances from their breeding grounds in the northern Rockies to their wintering grounds near the middle stretch of the Rio Grande. National Geographic Freshwater Fellow Sandra Postel writes about the spectacle.
Using innovative satellite technology, a new study finds that over a six-and-a-half year period groundwater supplies in the Central Valley of California, the nation’s fruit and vegetable bowl, dwindled by a volume of water equivalent to 63 percent of the capacity of Lake Mead, the largest reservoir in the United States.
“We’re using tomorrow’s water to meet today’s food demand,” warned Sandra Postel, National Geographic Freshwater Fellow, helping to provoke a meaningful discussion on water as it relates to food at the Aspen Environmental Forum. Agriculture was a central theme as it consumes a disproportionate share of global water resources.
