I have a collection that go back to 1965 , and I have be a subscriber for some 20 year . the magazine ; however , have become the province of the radical environmetalist movement . the editorial content lean heavily toward the left , and the choice and variety of article have degenerate over the year . even the quality of the writing have be erode as the magazine try to reach a wider audience with its leftist environmental propaganda . in sum , a great publication have be hijack by a group of irrational environmentalist who have little interest in any subject other than tree and the occasional politically correct topic .
