California needs to set more fires

popsci.com – From the 1930s to the 1970s, the Forest Service put out all fires on its lands, and state agencies followed suit in this fire suppression policy. But then, officials realized that extinguishing every ember had left mountains covered with leaf litter, twigs, and dense stands of trees—all of which enable fires to grow large and hot, clawing their way from the ground and into canopies. That’s why the officials in California and the West have been trying to return the forest to a more natural...
