Today's kids are increasingly disconnected from the natural world, says child advocacy expert Louv, even as research shows that "thoughtful exposure of youngsters to nature can...be a powerful form of therapy for attention-deficit disorder and other maladies." Instead of passing summer months hiking, swimming and telling stories around the campfire, children these days are more likely to attend computer camps or weight-loss camps: as a result, Louv says, they've come to think of nature as more of an abstraction than a reality...Louv argues for a return to an awareness of and appreciation for the natural world. Not only can nature teach kids science and nurture their creativity, he says, nature needs its children: where else will its future stewards come from?
