Arches National Park: What if you hiked all the way to Delicate Arch at Arches National Park and gazed out to see … oil pumps? For many visitors, the park’s dramatic, natural red rock architecture epitomizes our southwest desert. Yet, this uniquely American landscape could be permanently changed if oil and gas companies are allowed to begin drilling near the boundaries of Arches and the nearby Canyonlands National Park.

Biscayne National Park: If you go swimming in the sparkling blue waters of Biscayne National Park, teeming with a rainbow of fish, bottlenose dolphins, endangered hawksbill turtles, and other marine life, you may think you are vacationing on a remote, far-flung island.

Mojave National Preserve Mojave National Preserve and other California desert national parks are home to iconic Joshua tree forests and desert bighorn sheep. Unfortunately, they also serve as the epicenter of a new “gold rush” for industrial-scale solar proposals.

Yellowstone National Park Herds of bison grazing in Yellowstone’s Lamar and Hayden valleys are images that stay with visitors to the world’s first national park, long after their travels end. Unseen to the eyes of summer visitors are the unsightly images of hundreds of bison being rounded up and shipped to slaughter each winter or forced back into the park each spring by use of helicopters, pickup-trucks, and wranglers on horseback — all under management rules set by an outdated plan.

Yosemite National Park Views for miles and clean air to breathe deeply are two benefits that you and nearly four million annual visitors to Yosemite National Park count on – and are afforded by law.
