We oppose the construction of a solid wall along more than 700 miles of the United States / Mexico border. A wall that tears through border communities will cause terrible economic damage, impacting agriculture, ecotourism, retail sales, and private property. It will cause grave social harm, separating families and sending a terrible message to our neighbors. The route specified by the Secure Fence Act of 2006 will take it through National Wildlife Refuges, other parks, and riparian habitat critical for the survival of migrating birds as well as threatened and endangered species. The border wall will cost billions of dollars and even the Department of Homeland Security has said that it will only slow down, not stop, people who cross the border illegally.
