In addition to harming human communities, border wall construction has destroyed widespread areas of the nation’s most valuable wildlife habitat, including within national wildlife refuges, national monuments and wilderness areas. The U.S.-Mexico border runs through deserts with scant and unpredictable water supplies, where many animals live a precarious existence. An impenetrable barrier that stops them from finding the resources they need can threaten their survival.
If critical parts of the border are not reopened to wildlife, our country will lose substantial ground in our efforts to restore endangered species and conserve natural habitat in
the borderlands. Our considerable investments in federal conservation lands will be at risk.
