The Trump administration is threatening Big Bend National Park, a national heritage site, by planning to wall off river access points. This 517-mile sector, a vital part of the U.S.-Mexico border, faces imminent construction.

Such a wall would cut off wildlife from the Rio Grande, their sole water source, destroy cultural sites, and lock the river behind steel. This move reflects a disturbing disregard for public lands, seen as political vandalism rather than security.

Join the fight to protect Big Bend. Learn more at www.biologicaldiversity.org/campaigns/border_wall/. Contact your Congressional representatives at 202-224-3121 and urge them to strip federal funding for border wall construction in the region.

The first 20 miles of Trump's border wall have been constructed in New Mexico. This initial section was built using 2018 congressional funding, despite a 2019 government shutdown over wall

The first 20 miles of Trump's border wall have been constructed in New Mexico. This initial section was built using 2018 congressional funding, despite a 2019 government shutdown over wall appropriations.

Future wall construction is slated for Texas and California.

Urge Congress to deny further funding for this destructive border wall: https://bit.ly/2Gv75pi
