Turtles, abalone, shark fin and birds nest are top of the list of foods families feel compelled to order for their exotic qualities and expense, rather than necessarily for their taste.
The sad reality is, however, that 20 percent of shark species are now threatened, with an estimated 200,000 killed daily – millions every month – many for their fins alone. Some sharks, like the hammerhead and the great white, have been reduced by upwards of 70 percent in the last 15 years, while others, like the silky white tip, have disappeared from some oceans entirely.
Part of the problem, is the shocking practice of finning, which has been banned by upwards of 60 countries since 2004. Since sharks are large creatures and the meat itself is not particularly valuable, to save space on their boats, fishermen often slice the fins off the live shark on the high seas, tossing the body back into the ocean, where the shark in effect drowns.
This practice is fueled by huge demand. A “set” of dorsal and pectoral fins can fetch as much as $100 for fishermen, and then $700 a kilogram in Hong Kong’s dried seafood stores, the hub of the world’s trade.
Beyond the huge waste in a world where many are hungry and the cruelty of finning lies the reality that these wonderful and important creatures are disappearing from our oceans yet we can’t live without them.
Sharks and their direct predecessors have been swimming in the world’s oceans for well over 300 million years – long before dinosaurs walked the Earth. The fact that sharks have survived for so long without changing very much is a real tribute to the effectiveness of their anatomy.
And perhaps most importantly, sharks are essential to the ocean ecosystem. Like most top predators, sharks feed on the sick and weak, thereby keeping the schools of fish healthy. Lions and tigers serve the same role in their ecosystems, removing the weaker animals from the herds, and keeping the gene pool strong. |
