Wild Land Trust

The Wild Land Trust is the only nonprofit I endorse and support. 

The Wild Land Trust enables you to permanently rewild habitat for $1/sq.ft. on your own or as a gift. You'll receive unique GPS coordinates for your exact conservation.

The Wild Land Trust also helps organizations switch from suspect "carbon credit" schemes to square-foot conservation, which is transparent, perennial, and backed by solid science.

Planet of the Humans



Planet of the Humans battled both censorship and a smear campaign and won. The film landed global distribution in eight languages and an audience of over 30 million and growing.

Planet of the Humans went on to win the 2023 American Documentary Film Festival and was noted for its accuracy in scientific reporting. Here's a Free Ticket (if you like it, please give us a thumbs up on Prime).

Synopsis: Planet of the Humans dares to say what no one will - that we are losing the battle to stop climate change because we are following leaders who have taken us down the wrong road. This urgent, must-see movie is guaranteed to generate anger, debate, and, hopefully, a willingness to see our survival in a new way - before it's too late.

Ozzie Zehner, PhD

I'm the author of Green Illusions and producer of Planet of the Humans.

During the Obama Administration, I represented the U.S. Department of State as a reviewer for the Intergovernmental Panel on Climate Change (IPCC), serving under Secretaries Hillary Clinton and John Kerry.

I have held appointments at UC Berkeley and Northwestern University. I also referee books for MIT Press, write for various publications, and appear from time to time in the media and on college campuses. 

My research focuses on strategic ignorance, collective illusion, energy, and wild habitat conservation. I enjoy hiking and martial arts.

First Broadcast

This NPR interview was my first time on a national broadcast. I was so nervous.
