Having written about milk, salt, oysters, and frozen food, Kurlansky (Milk!: A 10,000-Year Food Fracas, 2018, etc.) turns his pen to an iconic fish on the brink of extinction.

“How many species do we lose when we lose a salmon?” asks the author toward the end of this handsomely illustrated work of natural history and environmental advocacy. The answer is that we do not know for certain, but the salmon is part of a chain of life that ranges from tiny insects to large mammals and birds. Every species, then, unlocks the door to many other species, and allowing any species to diminish is to threaten the whole web of life. So it is with the salmon. Kurlansky covers all the bases, from life cycle and reproductive history to the fact that the salmon is particularly vulnerable precisely because it spends part of its life in salt water, part in fresh water. The author observes that ideal salmon habitat includes rivers that run clear and clean and that are undammed, which are increasingly rare except in very remote places such as the Kamchatka Peninsula of Russia, which may turn out to be where salmon make their last stand. Certainly it won’t be on the Columbia River, where Lewis and Clark saw a horizon of flashing fins two centuries ago, whereas “by 1975, a total of 14 dams were blocking the main Columbia River, 13 were on the Snake [River],” numbers that don’t begin to take into account the thousands of smaller dams along the tributaries. Kurlansky offers a dauntingly long list of things that need to happen if the salmon is to be saved, ranging from dismantling dams to checking climate change, restoring forests and apex predators, ending the use of pesticides, and removing homes and roads from riverbanks in favor of galleries of trees. “If we can save the planet,” he writes, “the salmon will be all right." And if not, we must conclude, not.

In championing a critically important part of the natural world, Kurlansky sounds an urgent alarm that commands our attention.
