White-Shark-Bites on humans



As I know that shark bites occur more frequently in murky water and than in some place of Australia sea. They are attracted by lights, noise, or splashing, and smell. For theses reasons surface swimming should be kept to a minimum, in shark waters. Research shows that bright colors attract sharks more than dark objects, so it is better for divers to wear dark colors. Blood in the water can attract sharks from long distances. They can sense blood in the water in concentrations as little as 4 parts per million. Bleeding into the water by a diver or swimmer may not go unnoticed. Women who are menstruating are recommended to wear tampons. As to any evidence that the menstrual cycle can increase the hazard of shark attack is inconclusive. It is believed that sharks are only attracted by fresh blood of human being. So be aware with this one.

Many Shark's fine to be soup

The History of Shark Fin Soup:
The shark fin soup originated in Asia specially in China country and recipes date back over 2000 years. The soup was once a rarity available only to the aristocracy, primarily because it was so difficult to create. However, times have changed, fishing boats have improved, fishing nets are exponentially longer, and China's growing middle class has created an increased demand for this "delicacy." In daily, shark fin soup is routinely sold in trendy restaurants throughout Asia. Creating the soup is difficult because the fins must be cooked for a very long time until they separate into needles of cartilage that look like clear noodles. The fin itself has no taste, but is served with a broth of chicken, ham, and shiitake that it absorbs. Although numerous countries have made it illegal to harvest sharks for their fins, Hong Kong - Disney's new pal - is actually the world's largest trader of shark fins.
The shark fin soup is erroneously considered an aphrodisiac or regarded as beneficial to one's health, although studies have shown no healthful benefits. Ironically, the methods used to prepare shark fin soup reduce the water content of the fin, which concentrates numerous chemical impurities but the people there want not to know about this. Shark fins studied at the University of Hong Kong contained 5.84 parts per million (ppm) of mercury, compared to a maximum permitted level of 0.5 ppm. The high presence of mercury was confirmed in independent tests conducted by two state-related labs in Thailand, and the findings are also reflected in US, Australian, and New Zealand governmental reports.¹
In plain English, this means that eating shark fins could render men sterile due to the high mercury content. Shark fin soup is considered a delicacy by many. It the perfect example is man’s wanton killing of an ancient animal. Only the fin from the shark is used to make the soup and the rest of the live animal is discarded in the sea or thrown away.
In China, environmentalist groups Saturday protested against chain stores selling shark-fin soup as killing sharks for their fins can lead to their extinction. I am too deslike with the behaviour of China that alway use the fin of shark as their soup and food.
