Coral reefs are a microcosm of our planet: extraordinarily diverse, deeply interconnected, and full of wonders. Corals themselves are evolutionary marvels that build elaborate limestone formations from their collective skeletons, broker symbiotic relationships with algae, and manufacture their own fluorescent sunblock. But corals across the planet are in the middle of an unprecedented die-off, beset by warming oceans, pollution, human damage, and a devastating pandemic. Juli Berwald fell in love with coral reefs as a marine biology student, entranced by their beauty and complexity. Alarmed by their peril, she traveled the world to discover how to prevent their loss. She met scientists and activists operating in emergency mode, doing everything they can think of to save coral reefs before they disappear forever. Life on the Rocks is an inspiring, lucid, meditative ode to the reefs and the undaunted scientists working to save them against almost impossible odds.
