YOUNG LESS INTERESTED IN NATURE

TREE HUGGER - One would think that with growing environmental awareness and the rise of the green movement, tree huggers everywhere would be flocking to national parks. In fact, over the last ten years attendance at Yosemite has dropped 17%, Death Valley at 28%, and camping and back-country trips are down 24% overall. The Economist says " The importance of this decline can hardly be over-estimated for big environmental organizations such as the Sierra Club: they have depended on what one expert calls "a transcendent experience in nature", usually in childhood, to gain new members and thus remain powerful lobbyists for environmental causes."
