There are massive forest fires raging in Colorado and Arizona. These will shortly be continued by more massive forest fires in California and Oregon. Radical green efforts to block logging and timber sales in national forests since the 1990s are the real culprits. Another symptom of green obstructionism: widespread bark - beetle infestations. The U.S. Forest Service reported last year that during the last part of the 20th century, widespread treatments in lodge pole pine stands that would have created age class diversity, enhanced the vigor of remaining trees, and improved stand resiliency to drought, insect attack, and fires — such as timber harvest and thinning — lacked public acceptance.
