A new research shows that borderlands are synonymous with desolation and the Mexico-U.S. divide that spans nearly 2,000-miles could threaten biodiversity.
The paper, coauthored by Stanford biologists Paul Ehrlich and Rodolfo Dirzo, warns that some of the species in the continent’s most biologically diverse regions, including forests, grasslands and salt marshes face extinction within the U.S. if their movements are cut off by the continuous border wall President Trump has pledged to build.
Scientists point out that physical barriers not only prevent animals from accessing food, water, mates and other critical resources, but they also discourage them to move to different places within the same region by disrupting annual or seasonal migration and dispersal routes..
The paper calls on scientists around the world to support solutions, such as requirements that DHS identify species, habitats and ecological resources at risk from barrier construction and security operations; design barriers for maximum wildlife permeability where possible; and purchase or restore replacement habitat when environmental harm is inevitable. Nearly 3,000 scientists have signed on to endorse the paper’s message.
