A rallying cry and resistance manual from one of the leaders breathing new life into the environmental movement.
As the climate emergency worsens and biodiversity shrinks, we humans get used to it—we adapt, we normalize, we forget. Scientists call this “shifting baseline syndrome” and warn that it’s why we are increasingly sleepwalking toward disaster. In this positive and inspiring manifesto, the environmental activist and longtime editor-in-chief of Sierra magazine Jason Dove Mark offers an antidote, focusing on four simple but powerful rules that everyone can use to resist environmental amnesia: Go outside. Bear witness. Make a record. Pass it on. Mark makes the case for easy, everyday practices that can help us “remember the Earth” and support environmental conservation, restoration, and rewilding. And he shares moving examples of citizen scientists, birdwatchers, mountain climbers, and fishermen across the country who are putting them into practice. The Earth Said Remember Me is a hopeful, achievable prescription for protecting the planet, one citizen at a time.
Jason Dove Mark has served as editor-in-chief of Sierra and editor of Earth Island Journal. His writing has appeared in the New York Times, Los Angeles Times, San Francisco Chronicle, and the Atlantic. He lives in the Pacific Northwest.
Mark will be in conversation Mike Tidwell, a journalist, author, and climate activist living in Takoma Park, MD. His most recent book is an exploration of global warming’s impact in his own front yard, called The Lost Trees of Willow Avenue: A story of Climate and Hope on One American Street (St. Martin’s Press, March 2025). Publishers Weekly magazine named the book one of the best nonfiction books of 2025. A passionate conservationist, he founded the Chesapeake Climate Action Network in 2002, where he has led local and national campaigns for clean energy. He lives on Willow Avenue in Takoma Park, MD with his wife Beth and their cat Macy Gray.
