As the climate emergency worsens and biodiversity shrinks, we humans get used to it—we adapt, we normalise, 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 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.
