The environmental impact of border walls, explained.

When we talk about the consequences of the proposed wall at the border of the US and Mexico, we usually think in terms of people. But along the political divide are rich pockets of biodiversity, with dwindling populations of species that rely on the ability to move back and forth across the border.
Under the 2005 REAL ID act, the Department of Homeland Security doesn't have to comply with various environmental laws that might otherwise slow or halt construction in a sensitive area. Laws like the Endangered Species Act, the Clean Water Act, the National Environmental Policy Act or the Migratory Bird Treaty Act — none of those apply to border wall construction.
Several parcels of land, including the National Butterfly Center, a state park, and other areas in the federal wildlife refuge system — are still threatened by wall construction. It could still be years before construction starts in some of these areas — but there’s still a lot we don’t know about the full impact of barriers on biodiversity.
