The Trump administration is initiating oil and gas lease sales in the Arctic National Wildlife Refuge's Coastal Plain, inviting companies to identify drilling sites. This 1.56-million-acre area is the biological heart of the Arctic Refuge, vital for the Porcupine caribou herd, migratory birds, and polar bears.

Industrializing this irreplaceable sanctuary will harm wildlife and accelerate climate change. The Arctic is already warming four times faster than the rest of the planet. Drilling will displace animals, endanger polar bear families, and pollute air and water, fueling a climate disaster. Past lease sales have failed due to public demand for protection over short-term corporate profit. Stand up for the Coastal Plain.

The America the Beautiful Annual Pass, used by over a million visitors, grants entry to national parks and federal lands. The 2026 pass was legally mandated to feature a Glacier National Park photograph. However, the Trump administration instead inserted the president's image, reportedly discouraging sales and potentially voiding passes if the image is covered.

A new bill, the Prohibit Partisan Park Passes Act, seeks to ban images of living political figures on park passes. This aims to ensure public lands remain neutral spaces for all Americans, free from partisan politics.

U.S. residents should contact their representatives to support this act, ensuring passes feature natural beauty and wildlife, not political figures.
