The Center for Biological Diversity is again under attack. Far-right congressmen on the House Resources Committee have launched a baseless "investigation" against us for protecting the Arctic and polar bears from an oil conglomerate. Our Executive Director, Kierán, denounced this as a weaponization of government power, a smear tactic by oil-funded politicians to silence environmental advocates.

This "investigation" is a politically motivated witch hunt, devoid of legal merit and making absurd accusations. To combat this antidemocratic power-mongering and defend our critical work, we've established the Freedom Defense Fund. Your support is crucial to our survival against these persistent threats. Please donate today, or consider a monthly contribution to sustain our defense.

The Trump administration is initiating oil and gas lease sales in the Arctic National Wildlife Refuge's Coastal Plain, inviting companies to identify drilling sites. This 1.56-million-acre area is the biological heart of the Arctic Refuge, vital for the Porcupine caribou herd, migratory birds, and polar bears.

Industrializing this irreplaceable sanctuary will harm wildlife and accelerate climate change. The Arctic is already warming four times faster than the rest of the planet. Drilling will displace animals, endanger polar bear families, and pollute air and water, fueling a climate disaster. Past lease sales have failed due to public demand for protection over short-term corporate profit. Stand up for the Coastal Plain.
