For more than 400 million years, sharks have been swimming the world's oceans. - 130 million years before the first dinosaurs roamed the earth. Today, shark populations are declining at an alarming rate, and that is a real cause for concern. One of the causes is commercial fishing or what I would term as extracting the resources of the seas indiscriminately for profits only. Sharks are killed in large scales by unscrupulous fishermen. Humans have utilized sharks throughout history. Shark liver oil - Squalene is marketed and traded as an expensive ingredient in cosmetics and lotions. Squalene is also sold in the form of pills as health supplements, believed to be ideal for a healthy heart. It is believed scientifically that shark liver oil consists of about 60-85 % of this organic matter. However, plants like olives and the fruit of the oil palm also contain this substance, though in a lesser degree. The olive oil, received from the first compression, sharksnado holds about 400-450 mg/100g of squalene. Therefore, logically speaking, we do have a choice then, either to kill or to pluck, don't we?
Another reason is recreational fishing which is a popular 'sport' in many countries. Several species like blue sharks and short fin Mako sharks are targeted by recreational fishermen to win trophies of prestige. How can killing innocent animals be a sport, above all with elements of prestige in it? Soon these sharks will go into oblivion and our future generation will be denied knowledge of their existence. Besides, sharks have also been labeled as man-eaters, hence hunted in revenge of its attack on humans. No thanks to Steven Spielberg's 'Jaws', released in 1975, based on a novel by Peter Benchley. 'Jaws' overwhelmingly colonized the minds of movie watchers into accepting a myth that great whites are nothing but notorious man-eaters. Each year, humans kill more than 100 million sharks worldwide. This includes the tens of millions of sharks that are caught and killed annually for their fins, which are used in one of the world's most expensive seafood delicacies-the shark fin soup. Further statistics will continuously increase our worries if we include all the sharks caught into the fishermen's net as by catch.
Shark fin soup may remain as a delicacy for some who refuse to alter their taste buds and cravings for such a food cocktail made from anything but devoid of compassion and empathy towards another being, which co-exists in the same planet that we call home. The killing stops when the demand stops and again, the onus are left on us to preempt further destruction of our marine creatures. Malaysia for one has made a resolution, though not in official print, but through its tourism initiatives for Visit Malaysia Year 2016, under the Tourism Ministry of Malaysia to boycott all eateries that serve shark fin soup or any by-product of such nature. The east Malaysia state of Sabah in Borneo shall be commended for its rigorous effort in assuring tourists that they will not be having the leeway of patronizing outlets that serve shark-based products.
In some countries, shark body parts are sold as souvenirs. Recreational fishermen target large sharks to make a trophy from the jaws, which can sell for hundreds of dollars. Not only that, sharks' teeth are also another popular item found at souvenir shops, as well as small or baby sharks in jars of formaldehyde.
Nonetheless, coastal development has altered habitats. Many shark species use inshore coastal and estuarine habitats as a safe place for finding food, giving birth and growing up away from predators and competitors. This means that they are now vulnerable to negative changes in their habitat. Sharks are also affected by chemical pollution and environmental contamination. Pollution in the ocean either comes from land activities or directly deposited into the seas. In some cases, mercury has been found in several shark populations. The decline in marine lives, especially sharks, on the whole, directly points to one culprit - human activities.
Sharks must be protected. They help maintain a healthy ocean ecosystem that provides 1/3 of our world with food, more oxygen than all the rainforests combined, removes half of the atmosphere's manmade carbon dioxide (greenhouse gas), and controls our planet's temperature and weather. Sharks are also vital for the maintenance of healthy sea grass beds and coral reefs, feeding on other marine lives that overfeed on these food sources. Sharks keep other marine life in healthy balance and check by feeding on the sick or injured fish of a reef system, creating strong populations of fish and other marine life and regulate the oceans, by feeding on animals like seals which may overfeed on other fishes, if its blown population is left unchecked.
Sharks play a vital role at the top of the food chain by maintaining balance in the oceans. Destroying shark populations could destroy our oceans and our life support system. Additionally, they provide essential food sources for scavengers. Another benefit is sharks are great tourists' attraction. In some parts of the world, especially in island communities, swimming and diving with these magnificent animals are part of tourism activity packages that generate the growth of tourism revenue worth millions of dollars annually. That's why sharks are worth far more alive than dead. The domino effect of this development is that it provides job opportunities for the people, subsequently elevating their economy.
In conclusion, sharks today are facing the threat of extinction. It is estimated that nearly 100 million sharks are needlessly killed from the ocean each year. Scientists believe that if sharks become extinct we will essentially destroy the delicate balance that is necessary for the survival of thousands of marine species. Severe depletion of certain species is already revealing devastating effects in some areas of the world. Allowing the marine ecosystem to collapse is not an option for mankind. Considering the fact that at least one third of the oxygen we breathe, and a large percentage of the food we eat, come from the ocean, immediate change from present day practices must be enforced if we are to ensure a healthy future for all. Procrastinating is not an option here. We have the knowledge and means to implement sensible restrictions since we have partaken to the notion of being the superior being among all creations but will we actually make the changes necessary to avoid an otherwise looming environmental dilemma? Are we looking at anything but concerted effort and a stronger conviction here?
