Supporter,

The biodiversity crisis: 1 million species worldwide at risk of extinction. What's driving it? Habitat loss.

We're setting a goal of 100 new members to support our efforts to expand and secure permanent protections for wildlife refuges, public lands, and push back the fossil fuel industry from renting out these precious places for profit. Endangered species like polar bears, Florida panthers, American alligators, and West Indian manatees need us to fight for their right to thrive on these lands instead of letting polluters and special interests make record profits at the expense of their extinction.

The Arctic National Wildlife Refuge is the largest refuge in the country, and home to polar bears and other endangered species. Become a member today to keep oil and gas out of the refuge.

Florida Panther National Wildlife Refuge is one of the last remaining safe habitats for the endangered Florida panther. Become a member now to keep the refuge safe from development.

Extreme temperatures are killing off coral reefs at alarming rates, like this one that lives in the Palmyra Atoll National Wildlife Refuge. Join the Sierra Club now to stop warming waters and toxic chemicals from bleaching the oceans.

The Okefenokee National Wildlife Refuge is a biodiversity hotspot for threatened and endangered animals, but it’s at risk from nearby titanium mining. Join us now to keep it intact.

The Desert National Wildlife Refuge is home to endangered species like the desert tortoise, as well as Nevada's state animal the desert bighorn sheep. But it's at risk from expansion of a large Naval Air Station training ground. Become a member now to help keep the Desert Wildlife Refuge intact.

We can win these fights, but we can't do it without you. With time running out for all these places, your gift is more urgent than ever. We just need 100 gifts to make it happen: Donate today to protect wildlife refuges from all of the threats they face.
