In pictures, on CSI Miami, and to the naked eye the sea looks the same today as it ever did: blue, green or blue-green, rolling in glassy crashing curls, tormented then serene. It will look this way tomorrow, next year, arguably for eternity. No matter what freaks us out on earth, our species takes great comfort in knowing that the sea always looks exactly the same.
From up here.
But not down there. Not underneath. Under the swells and the sparkles and the froth, fathoms down, the globe's oceans have transformed over the last several decades, transforming even as we sit here into wastelands, ghost worlds, desolate deathscapes that could be filmed in situ for sci-fi films about the post-apocalypse. You won't find this out from a day at the beach. The smiling sea captain depicted on the fish-sticks box is keeping mum. But Canadian food journalist Taras Grescoe tells all in his important new book, Bottomfeeder (Bloomsbury, 2008).
"Rather quickly, the oceans are becoming environments unlike any we have ever known," Grescoe agonizes, giving as his first example the North Atlantic, where he watches Nova Scotian fishermen exulting over a new lobster boom while apparently neither knowing nor caring about its probable cause: human greed.
Yes, climate change plays a part but it's marginal compared to the massive overfishing required to supply restaurants and stores in a world that stuffs itself on tuna sandwiches, salmon steaks, shrimp cocktail and sashimi.
"The shallow waters off Nova Scotia used to be full of swordfish and bluefin tuna, as well as untold numbers of hake, halibut, and haddock. Cod in particular were the apex predators in these parts," Grescoe writes. (Later in the book, he quotes early observers describing "cod mountains" off a once-rich Newfoundland coast where the fifteenth-century navigator John Cabot reported cod populations so thick that they actually blocked his ships' passage.) Cod, Grescoe writes, once "prowled the gullies offshore in dense shoals, using their powerful mouths to suck up free-swimming larvae, sea urchins, and even full-grown crustaceans. But the cod were fished to collapse in the early 1990s. With the cod gone, stocks of lobsters and other low-in-the-food-chain species exploded." By wiping out predator species, the fishing industry screws up ecosystems. As sea creatures high on the food chain disappear, their populations more than decimated in the last half-century, a lobster boom "may just be a tiny blip on a slippery slope to oceans filled with jellyfish, bacteria, and slime."
Meanwhile, overfishing has created some 150 "dead zones" -- oxygen-free patches of ocean that can sustain no life -- around the world: Some of these patches, Grescoe tells us forebodingly, "are now as large as Ireland." In search of seafloor-dwelling species such as the trendy monkfish -- long ignored, then popularized singlehandedly by Julia Child in 1979 -- bottom-trawls weighing more than 26,000 pounds each rake and flatten wildlife-rich undersea peaks, leaving a paved-looking flatness in their wake. Oh, and a large percentage of coral reefs worldwide are dying or already dead. Oh, and those bluefin tuna and halibut steaks you like? Say it with me: Mercury. Those jumbo fried shrimp battened on pesticides and antibiotics in bacteria-riddled Chinese farms, their decomposing flesh treated with borax? How's your health insurance?
It is happening right this minute but not quite right before our eyes. This is exactly the sort of thing our species prefers not to think about. What kind of catastrophe is it? Take your pick. Ecological. Medical.
And ethical: Grescoe started this project as a diner, "a fish lover, but … no fish hugger" who has caught and eaten seafood eagerly all his life. But knowing as he does "that ours might be among the last generations in history able to enjoy the down-to-earth luxury of freshly caught wild fish," his fantasies of sampling Japanese pufferfish and Chinese "drunken shrimp" slam hard against reality:
"I draw the line," he resolves, "where the pursuit or cultivation of my dinner obviously damages the environment, where cruelty is involved, where pollution or adulterants make it unsafe to eat. I would get no pleasure from eating a nearly extinct songbird, wine made from tiger bones, or the last few grams of beluga caviar from the Caspian. For me, a pleasure that diminishes the experience of everybody else on earth is no pleasure at all."
Fair enough. So in this spirit of sad apprehension he set out around the world to report on the state of some of humanity's most celebrated seafoods and the communities surrounding their consumption: from Chesapeake Bay oysters to Japanese sushi to English fish and chips and beyond. Part detective, part adventurer, part whistleblower, he reveals underhanded practices, such as Japan's "scientific" whale fishing, and outright crime, such as tons of cod harvested illegally, exceeding official quotas, during their spawning season by Russian ships that offload their catch to other ships at sea in order to evade detection. (Greenpeace calls this "pirate fishing.") The results end up in myriad English "chippies," doused with salt and vinegar.
And we learn about "finning," the practice of slicing off just-caught sharks' pectoral and dorsal fins -- destined for soup -- with hot metal blades. "Kicked back into the ocean, alive and bleeding," it can take the sharks days to die. Nearly forty million are killed this way annually. Seventeen countries, including the US and Canada, now ban finning, but China and the EU are among the world's remaining avid finners; Grescoe identifies Spain as the most avid of all. Although shark hunting is technically forbidden in Galpagos National Park, a vast marine reserve, some 300,000 sharks are caught there every year. Until the 1960s, whitetip sharks were "the most abundant large animals on earth," Grescoe writes. "Forty years later they have all but disappeared from the Gulf of Mexico," where they once thrived. "Up the length of the Atlantic coast, the story is the same: since 1972, bull, dusky, smooth, and hammerhead shark populations have all been fished to one percent of their former levels." Who cares? Well, it's all about the ecosystems. Sharks eat skates and rays. Sans sharks, skyrocketing skate and ray populations are eating scallops and clams into extinction.
