The number of shark attacks in the US dropped from 50 in 2007 to 41 last year. Only 1 of those attacks resulted in death.
A shark attack is an attack on a human by a shark. Every year around 100 shark attacks are reported worldwide. Seventeen fatalities were recorded as having being caused by shark attacks in 2011, out of 118 recorded attacks. Despite their relative rarity, many people fear shark attacks after occasional serial attacks, such as the Jersey Shore shark attacks of 1916, and horror fiction and films such as the Jaws series. Out of more than 480 shark species, only three are responsible for two-digit number of fatal unprovoked attacks on humans: the great white, tiger and bull; however, the oceanic whitetip has probably killed many more castaways, not recorded in the statistics.
Shark finning refers to the removal and retention of shark fins while the remainder of the living shark is discarded in the ocean. Sharks returned to the ocean without their fins are often still alive; unable to move effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. Shark finning at sea enables fishing vessels to increase profitability and increase the number of sharks harvested, as they only have to store and transport the fins, by far the most profitable part of the shark. Some countries have banned this practice and require the whole shark to be brought back to port before removing the fins.
Shark finning increased since 1997 largely due to the increasing demand for shark fins for shark fin soup and traditional cures, particularly in China and its territories, and as a result of improved fishing technology and market economics. The International Union for Conservation of Nature’s Shark Specialist Group say that shark finning is widespread, and that "the rapidly expanding and largely unregulated shark fin trade represents one of the most serious threats to shark populations worldwide". Estimates of the global value of the shark fin trade range from US$540 million to US$1.2 billion (2007). Shark fins are among the most expensive seafood products, commonly retailing at US$400 per kg. In the U.S., where finning is prohibited, a bowl of shark-fin soup can sell for $70 to $150. Some buyers regard the whale shark and the basking shark as trophy species, and pay $10,000 to $20,000 for a fin.
A drum line is an aquatic device used to reduce the amount of shark attacks in popular beaches by capturing the shark on the drum line's hook. While most drum lines are used in addition to the shark net, it has been proven that the drum line is more effective at catching the three most dangerous shark species (Great white, Bull and Tiger). A shark net is a net that is left submerged underwater in order to capture potentially harmful sharks. The combination of drum lines and shark nets have been proven to be successful in reducing shark attacks in the areas protected by them. Since the shark nets and drum lines have been put into use, there has only been one death caused by a shark attack on a protected beach.

The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, and a federal district. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. The largest of these territories are Puerto Rico and the American Virgin Islands which are an official part of the United States. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the U.S. mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
