The Environmental Impact of the U.S.-Mexico Border Wall

A line of 18-foot-tall steel posts placed four inches apart cuts like a scar across the Lower Rio Grande Valley National Wildlife Refuge near McAllen, Texas. It’s a stretch of a barrier extending intermittently across 650 miles of the U.S.-Mexico border from California to Texas, and presidential candidates Ted Cruz, Donald Trump and Marco Rubio vow to enlarge it if elected.

The barrier is intended to deter illegal immigration and smuggling. Whether it has achieved those aims remains unclear, but what is clear in this part of Texas is that sections of the barrier bisect and isolate public and private lands, threatening to decimate wildlife habitats and leaving communities on both sides of the border that rely on wildlife tourism to wither.
