Jer Collins is a climber and an illustrator, and somebody asked him to bring his sketchbook down the Amazon and draw the people living along it. That trip opened the door to mixed-media storytelling, and he kept going — the Arctic National Wildlife Refuge, Nepal, Bears Ears, the redwoods. How much did I love this book? We excerpted it in Adventure Journal. Jer’s organizing idea: A sequoia starts as a seed you could lose in your palm, so he goes looking for people working at that scale who are growing something enormous. Céline Cousteau, still at it two generations on. Prem Kunwar teaching and organizing in Nepal. Wendy Baxter, who climbs giant trees for a living and started the Ancient Forest Society. Gwich’in people fighting drilling on their own ground. The pages are ink, watercolor, collage, photographs, and handwriting all at once, and it doesn’t run in a straight line — you can open it anywhere.
