Scientists warn that proposed US-Mexico border wall threatens biodiversity, conservation

Amidst increased tensions over the US-Mexico border, a multinational group of over 2500 scientists have endorsed an article cautioning that a hardened barrier may produce devastating ecological effects while hampering binational conservation efforts. In the BioScience Viewpoint , a group led by Robert Peters, William J. Ripple, and Jennifer R. B. Miller call attention to ecological disturbances that could affect hundreds of terrestrial and aquatic species, notably including the Mexican gray wolf and Sonoran pronghorn.
