Our landmark national parks are under siege: A dozen areas in the national park system already house oil and gas operations, and 30 areas may be threatened by drilling in the future.

This means our cherished public lands face severe air and water pollution, the animals and plants that depend on these lands will experience devastating habitat loss, and people who spend time on these public lands will see their health threatened and their experience of nature degraded.

Theodore Roosevelt and Grand Teton national parks are just two cherished places threatened by the rapid expansion of oil and natural gas drilling and fracking. Nationwide the Bureau of Land Management estimates that 90 percent of new oil and gas wells on federal land are fracked.

But the Bureau’s new draft fracking rules are even weaker than in the past. Sadly, these regulations seem designed to encourage as much fracking as possible, while doing little to protect the environment or people’s health.

Now’s our chance to ensure the feds take real steps to protect our national treasures. Tell the Bureau of Land Management to ban fracking on our public lands.
