BOSTON ( TheStreet) -- Our national wildlife refuge system is a big moneymaker, pumping more than $24 billion into the economy every year and supporting more than 35,000 jobs, the U.S. Fish and Wildlife Service says. The report comes at a time many polls have shown a growing disconnect between people (both adults and children) and the natural world. The phenomenon has reached such a supposed fever pitch that writer Richard Louv even coined a term to describe it -- nature deficit disorder -- in his 2005 book, Last Child in the Woods. It would seem national wildlife refuges offer more than a glimmer of hope that people's interest in nature and wildlife is not only not dead, but robust enough to turn a healthy profit. The findings of the report, Banking on Nature, were unveiled this month by U.S. Secretary of the Interior Sally Jewell during a visit to the Minnesota Valley National Wildlife Refuge.
