During Donald Trump’s first presidential term, he began an ambitious and costly border militarization program, including the construction of over 450 miles of wall that severed wildlife corridors and fragmented ecosystems in some of the country’s most remote and biodiverse regions. With his second inauguration on Monday, environmentalists are bracing for any new phase of construction that could exacerbate the ecological toll of the border wall.
“It’s an absolute travesty and a disaster for border wildlife,” said Margaret Wilder, a human-environment geographer and political ecologist at the University of Arizona, regarding the environmental impact of the existing border wall and the prospect of renewed construction. She said the wall harmed efforts “after many decades of binational cooperation between the US and Mexico to protect this fragile and biodiverse region. I don’t think Americans realize what is at stake.”
