Friend,

There's one reason we still have bald eagles in our skies, grizzly bears in our mountains, and humpback whales in our oceans today. It's the Endangered Species Act (ESA) — one of the most important pieces of conservation legislation in our history. And soon, the beloved Monarch butterflies will join the list.

The Endangered Species Act (ESA) is under attack, and we still need it more than ever. Despite its success in saving species from extinction, we’re facing the first mass extinction caused by human activities. Habitat destruction, climate change, and other threats put our most cherished wildlife at risk. Without the ESA, these protections could be lost. We need your help NOW to fight back and preserve the vital safeguards that protect imperiled species from being driven to the brink.

Make a gift to the Sierra Club to celebrate the 51st anniversary of the Endangered Species Act and power our work to protect wildlife. Right now, your donation will be matched 5X – giving every $1 the power of $5!

Wildlife populations worldwide are crashing at alarming rates, largely due to habitat destruction, climate change, and overexploitation. 3 billion birds have vanished in North America since 1970, animal populations have dropped 60% globally since 1970, and 1 million species could face extinction by 2050. The numbers are staggering.

The Endangered Species Act proves that when we commit to conservation — when we invest in protecting the animals we care about — we can do so much good. In the half-century since it was passed, 99% of species listed under the Act have been saved from extinction.

We need bold, decisive action now to defend the Endangered Species Act and protect the ecosystems vulnerable species depend on. Attacks on the ESA threaten the very protections that have helped save countless species from extinction. We must fight back against these efforts, ensure the Act remains strong, and hold lawmakers accountable. Protecting the ESA is critical, as it is our best tool for safeguarding endangered species and their habitats from the growing threats they face, including habitat destruction and climate change. The time to act is now.

Your gift today will do five times as much to strengthen the Sierra Club's vital work for endangered species and the environment — don't miss out on this chance to make 5X the impact!
