AMA with Stanford biologist Paul Ehrlich: How the Border Wall Threatens National Security
A Border Wall Threatens Our National Security
The continuous border wall President Trump has pledged to build could cause the extinction of various plant and animal species, damaging natural services to people and local economies in the process. It would be a crime against biodiversity.
I am co-author of a recently published analysis that outlines how physical barriers prevent or discourage animals from accessing food, water, mates and other critical resources by disrupting annual or seasonal migration and dispersal routes.
Nearly 3,000 scientists have signed on to endorse the paper’s message, which includes a call for solutions such as requirements that the U.S. Department of Homeland Security 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. (rjordan@Stanford.edu will be posting my responses to questions)
Read about the Stanford Center for Conservation Biology, which I lead.
