You’ve heard, haven’t you, that the world will be without salt-water fish by the year 2050. It’s hard to believe, isn’t it? Start believing, this book calmly, and very nerdily, walks you through exactly how it will happen. Or, you might ask yourself, ‘how could we let this happen?’
World Without Fish, by former commercial fisherman Mark Kurlansky, is a lovingly-illustrated book for ages nine and up. The drawings inside were done by Frank Stockton. The book is only 170 pages and it reads like a graphic novel, quickly and easily.
Kurlansky starts by giving a brief outline of the problem. The first thing likely to make fish go extinct is overfishing. Technology has made it impossible for fish to hide from the modern fisherman.
Whereas before, sailors used sails (even right up to the 1950s), now the modern fisherman has electric motors, beam trawls and giant funnel nets that have 14,000 times the capacity to pull up fish that old sailing fleets had. With the invention of plastic monofilament for netting, and bouncy ‘rock hoppers,’ fisherman can drag their nets right along the bottom of the ocean floor giving fish no place to hide, not even between rocks, because the rubber rollers would hop right over rocks and scrape the bottom more closely.
So tightly regulating fishing is an important step. Still, even doing that, the fish are disappearing. Water pollution is the next culprit. Damage in the ecosystem from oil spills has been recorded decades after the spill. It gives fish and shellfish abnormal characteristics, such as the inability to reproduce. When crabs try to burrow into sand, they hit a layer of oil and have to go sideways instead. Remember that BP oil spill in the Gulf of Mexico? That was equivalent to an oil tanker disaster every single day for three months. Farmers also contribute to the dead patches of ocean that are forming in places like the Gulf of Mexico, when their farm pesticides and chemicals reach open waters via rivers like the Mississippi, and then down to the Gulf.
The third thing that could make fish go extinct is global warming. Kurlansky says that folks think that because land is so fecund in warm, tropical areas that people believe oceans would be too. But it is the opposite. Fish love cold seas. Specific temperatures signal to fish it is time to reproduce. With the fast-changing warming of the planet, fish don’t get that signal. Fish need not only a specific temperature, but also a specific degree of saltiness. As ice melts in the Arctic, it changes the saltiness of the water.
Kurlansky believes that humans are more in touch with protecting mammals, which are more like ourselves, than a different kind of animal, like fish. Alas, If fish go extinct, sea birds will shortly follow.
Kurlansky has some ideas for the reader of how we can stop or slow down this process. I’ll let you read the book to get his list.
If you don’t think of this as an emergency, it’s a good thing I have this book school library collections, isn’t it? Kurlansky says today's students are the most important generation of humans ever. Survival of humanity will be up to the kids in schools today as their adults aren’t treating these issues AS an emergency.
Upon reflection, this book makes me shudder to think of how public school library funding worldwide isn’t coming close to stocking titles that can educate the next generation about the challenges our species, and other species will face.
