Sharks are probably the most misunderstood creatures on this planet. Feared by most, these creatures lack the much needed lobby to stop their on-going slaughtering. The killing of sharks is one of the biggest ecological time bombs. A bomb that will go off if not defused in time. Sharks have been around for over 400 million years, making them one of the most successful creatures in the animal kingdom with humans as the only true threat for their very existence. It is estimated that over 150 million sharks are killed each year because of their fins, as by-catch or through "sport" fishing. (Sharkschool)
