Life on the Rocks

The story of the urgent fight to save the coral reefs, and why it matters to us all

Coral reefs are a microcosm of our planet: extraordinarily diverse, deeply interconnected, and full of wonders. When they're thriving, these fairy gardens hidden beneath the ocean's surface burst with color and life. They sustain entire ecosystems and protect vulnerable coasts. 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. She was so amazed by the ingenuity of these last ditch efforts, she joined in rescue missions, unexpected partnerships, risky experiments, and rebuilt reefs with rebar and zip ties.

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. As she also attempts to help her daughter in her own struggle with mental illness, Berwald explores what it means to keep fighting a battle whose outcome is uncertain. She contemplates the inevitable grief of climate change and the beauty of small victories.
