A SEA FULL OF TURTLES

An aquatic ecologist recounts his search for reasons for optimism in the face of looming extinction crises.

When Covid-19 lockdowns closed seaports, Streever, author of Cold and Heat, and his wife, a marine biologist, were at sea aboard their restored sailboat Rocinante. Cleared into a Mexican port, they spent the next several years sailing in the Gulf of California, off the Baja peninsula, where five species of sea turtles now exist. Noting that “engaging with those who make a living from the sea is a necessary part of the conservation movement,” the author interviewed the volunteer "turtlers" who find and protect turtle nests, nonprofit professionals working to promote biodiversity, a veterinarian who performed a necropsy on a dead turtle, and local fishermen. He found that the gulf area suffers from “inadequate enforcement of mostly existing regulations and a lack of opportunities for people aside from fishing.” Though the region is “one of the five most productive marine ecosystems in the world,” it has become "a badly diminished sea." Streever zeroes in on the fate of sea turtles, but his larger concern is existential. If we conceive of the history of life on Earth as a 24-hour day, he writes, humans’ attention to the conservation of our fellow species has only arisen “a mere few seconds before midnight.” Sea turtles and other "charismatic endangered species" can serve to "draw our attention, help us change our ways." Streever makes a convincing case, based on firsthand observations, that we are overdue for a major course correction. Even if humans have proven to be the species most responsible for extinction events, the author still ends on a hopeful note, and his creed of "optimistic environmentalism" becomes something other than a confounding oxymoron.

A hopeful consideration of the beauty and fate of wild sea turtles—and the natural world as a whole.
