Borderlands

Walls and barriers have already been constructed across more than 650 miles of the U.S.-Mexico border. These barriers block wildlife migration, cause flooding and damage pristine wild lands, including wildlife refuges, wilderness areas, and national forests. Sierra Club Borderlands advocates for real solutions, such as comprehensive immigration reform with a path to citizenship, that address the root causes of complex border problems.
