Down to Earth

Lake Powell and Lake Mead are two massive man-made lakes, and they’re reservoirs for water used all over the West–for agriculture, residences, industry, electricity, and wildlife. And they’re running low on water–we’re taking out more than they’re being replenished. Brian Richter, president of Sustainable Waters, and author of the book, Chasing Water: A Guide for Moving from Scarcity to Sustainability, talks about the roots of the problem, and what we can do about it.
