The construction poses significant environmental and social risks. Big Bend National Park, a protected area since 1944, is home to unique wildlife and ecosystems that could be irreparably damaged by the project. Local residents and environmental groups fear the destruction of natural habitats and the disruption of tourism, a major economic driver in the region. Additionally, the project has sparked legal challenges and protests, highlighting widespread opposition to the wall's expansion. Critics also worry about the long-term implications for U.S.-Mexico relations and the precedent set for future infrastructure projects in protected areas.
