What Will California Do With Millions of Dead Trees?

Due to drought, bark beetles, and devastating forest fires, at least 12 million California trees are dead, according to the U.S. Forest Service. That’s a conservative estimate, though; Gregory Asner of Stanford University recently concluded that roughly 120 million—about 20 percent of the state's forests—are doomed, even with a mighty El Niño.

A major question now is how to remove the trees that pose the highest risk to humans.
