Coral reefs are a microcosm of our planet: wondrously diverse, deeply interconnected, and critically imperiled. They sustain entire ecosystems and protect vulnerable coasts. But corals across the planet are in the middle of an unprecedented die-off, beset by warming oceans, pollution, human damage, and their own devastating pandemic. Even under stress, they are out-of-this world gorgeous, sending out warning flares in fluorescent bursts of yellow, pink, and indigo. Juli Berwald fell in love with coral reefs as a marine biology student, entranced by their beauty and complexity. While she was concerned by bleaching events and coral disease, she didn't fully understand what a dead reef meant until she experienced one on a dive: barren, decaying, and coated in slime. Deeply alarmed, she traveled the world desperate to discover how to prevent their loss. Life on the Rocks is a meditative ode to the reefs and the undaunted scientists working to save them against almost impossible odds. Berwald explores what it means to keep fighting a battle that can't be won, contemplating the inevitable grief of climate change and the beauty of small victories.
