President Trump signed an executive order on Wednesday pushing ahead one of his signature campaign stumps—the construction of a massive $14-20 billion wall along the 2,000-mile-long border with Mexico, designed to deter illegal immigrants and drugs from entering the United States.

The wall has faced fierce criticisms from human rights groups for the possible humanitarian disaster it could cause (ask Berlin about this). But if built, the wall could pose another threat altogether: ecological disaster.
A barrier would sever animal populations living in the fragile desert ecosystems of the US-Mexico border from food resources, mates, and important migration routes. Such a disruption would deal an irreparable blow to countless species, including extraordinarily rare ones like the Sonoran jaguar and Mexican gray wolf.
Man-made barriers like roads and fences are some of the most devastating types of development to wildlife.
According to a US Fish and Wildlife Service provisional report released last year, a Trump wall covering the entire 2,000-mile border, with approximately 1,000 feet of developed space on either side,would potentially impact 111 endangered species, 108 species of migratory birds, four wildlife refuges and fish hatcheries, and an unknown number of protected wetlands.
