I’m writing on behalf of the Center for Immigration Studies, a non-profit research organization based in Washington D.C. that studies the costs of immigration on the American public, and Sheena Rodriguez, a citizen of Texas in response to Customs and Border Protection’s “Rio Grande Valley Border Barrier System Project Request for Input.” The greater environmental danger, both in this area and in Texas as a whole, to threatened or endangered plant or animal species, recreational activities, the daily lives of local citizens, impacts to local businesses, historical sites and areas of cultural significance is the border crisis itself, not construction undertaken to build barriers that would stop the crisis. The idea that the construction of a barrier to prevent a border crisis has environmental consequences, but a border crisis itself has no environmental consequences is ludicrous.
