Working as an organic farmer, activist, and editor of Sierra magazine, Jason Dove Mark has spent twenty-five years trying to make the world more livable. In his second book, which weaves memoir with science, he’s concluded the biggest obstacle to solving the compounding effects of climate change is blithely accepting ever-worsening “new normals” in the environment. He’s talking about shifting baselines, a clinical term for forgetting how bountiful nature used to be. In this forgetting, we become deadened, he argues, the way “a freak heat wave can go from whoa to meh in less than a decade.” But all is not lost. Baselines can shift in the right direction. He argues for four action steps (with real-world success examples of each): Go outside, bear witness, make a record, and pass it on. Want inspiration? Here it is.
