When praying to God this Sunday, the psalmist acknowledges our mortality in stark terms: “You turn man back to dust.” It appears that humanity is doing a pretty good job of its own on the dusting front, with people around the world living in increasingly dry, dusty, water-stressed cities.

“We can and must take back our environment, including our water environment.”

Approximately 400 billion gallons of water are used in the United States per day; nearly half of that is used for thermoelectric power generation.
