Deep Water: The World in the Ocean

This expansive report from novelist Bradley (Ghost Species) studies ocean ecosystems as a means of exploring the interconnectedness of life on Earth. Emphasizing the fragility and complexity of ecological communities, Bradley notes that the industrial-scale slaughter of whales in the early 20th century counterintuitively resulted in an 80% drop in the krill population because whale “excrement provides vital nutrients for the phytoplankton upon which the krill depend.” Fish are more sophisticated than they’re given credit for, Bradley contends, citing research that found “rainbowfish learn to associate signals with food... twice as fast as dogs” and that sticklebacks ostracize group members who don’t take their turn in the vulnerable position at the front of the school. Such studies underscore what will be lost if humans don’t rein in climate change, Bradley argues, discussing how rising sea levels are endangering Australian sea turtles by submerging their traditional breeding grounds. Bradley weaves natural history, climate studies, and trivia into an elegant whole that drives home the dire threat global warming poses to the ocean, all delivered in plaintive prose (“The toxic legacies of human industry written into the bodies of ocean creatures are a reminder that the deep is not a place of forgetting, but an ark of memory”). It’s a galvanizing call to action. Agent: Camilla Bolton, Darley Anderson Literary. (July)
