New border wall construction in California threatens some of the Southwest’s most fragile ecosystems, cutting through habitats that wildlife depends on for survival. From endangered mountain lions and bighorn sheep to migratory birds and desert pollinators, many species rely on open migration corridors to find food, water, and breeding grounds. Expanding barriers across deserts, mountains, and protected public lands fragments habitats, disrupts movement, and accelerates biodiversity loss as climate change places increasing stress on native species. Construction activities, including blasting, road building, and groundwater disruption, can leave lasting damage on ecosystems that have taken centuries to develop.

Congress must investigate environmental damage, threats to cultural resources and public safety, allegations of civil rights violations and harassment of citizens on public lands, and potential corruption in border wall contracting. Lawmakers should ensure full transparency, accountability, and compliance with environmental, civil rights, and cultural resource protection laws, and hold agencies and contractors responsible for any misconduct or misuse of taxpayer funds.

Sign the petition to urge Congress to Save The Wild and Stop The Wall.
