Tuna: you can almost taste the extinction in each bite!


Tuna fish, (not to be confused with actual “chicken” or ‘chicken of the sea’ as in Jessica Simpson’s case) is one of the great marvels of the oceans. It is considered one of the most evolved fish in the world. Bluefin tuna, for example, can reach speeds of up to 88 km per hour. Along with Mako sharks and Great Whites, the bluefin tuna are homoeotherms; animals that are capable of internally regulating their body temperatures. They are capable of elevating their body temperatures by as much as 25 degrees above the water they swim in, thus making them particularly effective as predators. Bluefin Tuna can migrate across the Pacific and Atlantic Oceans, then turn around and do it again.

The bluefin tuna, and to a lesser extent, the yellowfin, are among the most sought-after of big-game fishes. Tuna is the most popular food fish in the world. It is eaten raw, cooked, in sandwiches, in salads, and in cat food. The total worldwide tuna harvest is four million tons. Commercial over fishing, almost exclusively to feed the insatiable Japanese sashimi market, has endangered all populations of bluefin tuna.

The WWF (not the wrestlers you idiot) are predicting that Mediterranean Bluefin Tuna will be extinct by 2012. They have stated that, "The population of tunas that are capable of reproducing – fish aged 4 years or over and weighing more than 35kg – is being wiped out." Ransom Myers, a marine biologist from Dalhousie University in Halifax, Nova Scotia, has pointed out the fact that industrial fishing took no more than 10-15 years to virtually liquidate and imperil any new fish community it encountered to a tenth of its previous size. "From giant blue marlin to mighty bluefin tuna, and from tropical groupers to Antarctic cod, industrial fishing has scoured the global ocean”. In fact, scientists predict that the collapse of all ocean fish stocks by 2048.

In a 2003, Dr. Myers published an article in the journal Nature and stated,

Most people also don't know how bad it is for us to be eating so much fish, not only because of the destruction of an ecosystem vital to survival but also because the big predatory fish are full of the toxins and other pollutants that we cast into the oceans. It's not as healthy to eat fish as most people believe.

Due to the ferocious demand for bluefin tuna from Japan where bluefin tuna are considered a delicacy and are used in sushi and sashimi, overfishing is posed to drive the species into extinction. The Economist magazine has an article stating that Monaco, with support from European allies France and Britain, along with the USA are pushing forward in 2010 to have an international ban on the sale of bluefin tuna.

As Prince Albert, Monaco’s ruler, wrote in the Wall Street Journal last month, “The forces of selfishness and stupidity that wiped out the great whales and the northern cod in the last century are steaming ahead at full speed... The bluefin tuna is as endangered as the giant panda and the white rhino.”

Once the oceans have been systematically deprived of life and ecosystem after ecosystem begins to fail, terrestrial environs will also collapse and human civilization too will cease due to our own greed.
