Question

Sharks have gained unfair reputation for being large fierce sea animals. That humanity’s unfounded fear and hatred of these ancient creatures are leading to a worldwide slaughter (大屠殺) may result in the extinction of many larger, coastal shark species. The shark is the victim of a warped (有偏見的) attitude of wildlife protection; we strive (努力) only to protect the beautiful, non-threatening parts of our environment. And, in our efforts to restore only non-threat parts of our earth, we ignore other important parts.

A perfect illustration of this attitude is the contrasting attitude towards another large sea animal, the dolphin. During the 1980s, environmentalists in the United States objected to the practice of hunting tuna (金槍魚) in the Pacific Ocean since these nets also caught dolphins. The environmentalists generated enough political and economic pressure to prevent tuna companies from buying tuna that had been caught in drift nets. In contrast to this effort, the populations of sharks in the Pacific Ocean have decreased to the point of extinction and there has been very little effort by the same environmentalism to save this important species of wildlife in water. Sharks are among the oldest creatures on earth, having survived in the seas for more than 350 million years. They are extremely efficient animals, feeding on wounded or dying animals, thus performing an important role in nature of knocking out the weaker animals in a species. Just the fact that species such as the Great White Shark have managed to live in the oceans for so many millions of years is enough proof of their efficiency and adaptability to changing environment. It is time for humans, who may not survive another 1,000 years at the rate they are damaging the planet, to cast away their fears and begin considering the protection of sharks as creatures that may provide us with an insight into our own survival.
