Fighting wildfires in America cost federal agencies almost $2 billion last year including more than half the budget of the U.S. Forest Service. Wildland fires are growing worse in a time of drought and climate change, and the biggest and most destructive fires can’t be stopped. They are a force of nature: imagine trying to stop a hurricane. Yet the government has to try, because more than a 100 million Americans now live in — or near — forests and grasslands that can erupt in flames. This is what’s left of a neighborhood in the Kern River Valley.
