THE FOREST IN THE SEA

Seaweed’s impressive mysteries and surprising potential.

Conversationally addressing readers, Sanchez adeptly conveys fascinating facts (“seaweed is as different from land plants as a bird is from a fish”) about her subject. Short sentences, accessible vocabulary, lively comparisons (e.g., drawing parallels between sea and avian predators like sharks and hawks), and revelations—like learning that seaweed affects even those who don’t live right by the ocean because it sustains air and water and provides food—will keep readers absorbed. Gleaming color photos are engaging and sometimes amusing, like a beach-strolling Holstein; cows have a big role in this book. There’s also some mystery (what is seaweed, exactly?), history (seaweed fossils; more recently, using Irish moss as fertilizer), and reimagining (Sanchez invites readers to see seaweed as an underwater forest). Climate change, inevitably, plays a role in this work, and some harmful potential of algae is noted, but seaweed’s positives (in the creation of bioplastics, medicines, and, especially, food) dominate. Finally, the book adroitly returns to the people, cows, and a question introduced in the first pages. The last chapter cites other potential uses (fuel, insulation, paper), celebrating seaweed’s future.

Fact-loving, sea-loving, science-loving, and just plain curious readers will find much to chew over here.
