The record-breaking wildfire in Yosemite National Park is almost fully contained, two months after it started. The blaze calls attention to a problem across the western U.S.: After a century of having its fires routinely extinguished, the forests are overloaded with fuel.
A heated debate has flared up about what to do with that forest fuel. California is hoping to reduce its fire risk through renewable energy, but some worry about the environmental costs of thinning the forests.
The Rim wildfire that began three weeks ago today is now 80 percent contained, officials say, but it has burned more than a quarter of a million acres, and it may continue to grow, thanks to low humidity and other conditions.
