More than 1,700 species are protected under the #ESA — with many more awaiting protections. The Act has saved 99% of species under its care, yet Congress is once again trying to weaken this lifesaving law — this time under the guise of helping renewable energy. Take action 🔗⬇️ bit.ly/4AM4ksi

TODAY is your LAST CHANCE to speak up to protect the Roadless Rule. The public comment period closes TODAY, Oct. 6. This is just a small glimpse of who these roadless wild areas protect — from colorful candy darters to mighty grizzly bears. These species all deserve a safe place to call home.

In a bittersweet move for conservation groups, the FWS just agreed to issue a final listing determination for monarch butterflies by June 6, 2030. It will have taken over a decade and a half for monarchs to get thee protection they need, but it's a victory to finally have a binding date 🦋🦋

We're taking the Trump admin. to court to stop it from allowing endangered species to be killed. In September, FWS director, Brian Nesvik, issued a directive attempting to strip imperiled wildlife of protections from activities that can harm or kill them. In the #ESA, this is known as "take."

Under the guise of helping renewable energy, a new legislative package, cynically titled the "Bipartisan American Affordability and Jobs Act of 2026," would give the fossil fuel industry massive long-term structural advantages and lock in thousands of fossil fuel projects.

Trump’s DOT just finalized a rule gutting CAFE standards, which conserve billions of gallons of gas and save consumers billions at the pump. These standards were the biggest single step any nation has taken to save gas, money at the pump, and auto #pollution. Learn more 🔗➡️ bit.ly/47lQaAz

Another cruise ship has docked in Alaska with a dead endangered fin whale on its bow. 💔 Ships can kill these swimming giants in an instant as they hurtle through their habitat, and these collisions are one of the most frequent causes of premature death for several highly endangered marine mammals.

ICYMI: Wyoming’s wolf hunting season begins tomorrow, putting Mollie’s Pack and other Yellowstone wolves at risk of being killed by trophy hunters the moment they cross the invisible boundary of the park.
A text block centered over a blurred background. The text is a quote from Kristine Akland, our Northern Rockies director. It reads "Yellowstone’s longest continuously existing wolf family could be dead within weeks if Wyoming doesn’t step up to protect them. Mollie’s Pack has been studied by scientists and enjoyed by visitors for decades. It would be a massive loss for Wyoming and the millions of Yellowstone visitors if Wyoming Game and Fish let them be killed this hunting season."

The whims of one person shouldn't control the fate of an entire species. But Trump just signed an executive order directing the Dept. of the Interior to consider delisting gray wolves nationwide and Mexican gray wolves in the Southwest — and push states with species-protection laws to do the same.
