'Tucked into the fiscal relief package for Puerto Rico this spring was a provision to give away a national treasure that belongs to all Americans — 3,100 acres of the Vieques National Wildlife Refuge. The proposal had nothing to do with the economic recovery of Puerto Rico. But it would have handed an important victory to extremists in Congress and state legislatures who want to grab national lands and turn them over to the states to be drilled, logged or sold to the highest bidder. . It was only one of several efforts in Congress to dismantle the nation’s system of more than 560 wildlife refuges and 38 wetlands totaling about 150 million acres of land and water. Opponents of federal land ownership also want to give hundreds of millions of acres of forests and rangelands to cash-hungry states or territories. If they succeed, not even the national parks will be safe.
