Could have been great
Reviewed in the United States on March 8, 2020
As a professional marine biologist (now retired) and once-avid freediver who did nearly all of my underwater fieldwork without SCUBA, I looked forward to reading this book. Alas, the author greatly diminishes a fascinating subject by embellishing it (unnecessarily!) with endless hyperbole. Two examples (from just one page that contained SIX such mistakes): "How algae can generate so much oxygen...nobody knows." "Coral can communicate in a way far more sophisticated than anyone ever thought." Neither of these statements is true: A great many people know, in exquisite detail, exactly how algae (and land plants) generate oxygen; anyone can read about it in the literature. And coral "communication" remains poorly understood but it's unlikely to be very sophisticated; the author mistakes corals' abilities to synchronize INDIVIDUALLY with predictable environmental variation (temperature, tides, phases of the moon) with an ability to communicate/synchronize with ONE ANOTHER (no evidence); again, anyone can read about it. Seems to me that either the author did far too little homework, or he had too little interest in the TRUE wonders of nature.
