Inspired by recent data on shark deaths, two data visualization heavyweights have created a stunning infographic to put the numbers in perspective.
A recent report published in the journal Marine Policy revealed that an estimated 100 million sharks are killed by humans every year. The paper added that the number of sharks killed could actually be anywhere between 63 million and 273 million.
In stark contrast, only 12 humans were killed worldwide by sharks in 2011, according to National Geographic.
In a 2009 report, the International Union for Conservation of Nature noted that one-third of open ocean sharks are threatened or near-threatened with extinction due to overfishing.
A recent report published in the journal Marine Policy revealed that an estimated 100 million sharks are killed by humans every year. The paper added that the number of sharks killed could actually be anywhere between 63 million and 273 million.
Based on an analysis of average shark weights, this translates into a total annual mortality estimate of about 100 million sharks in 2000, and about 97 million sharks in 2010, with a total range of possible values between 63 and 273 million sharks per year.
The first study to determine the global conservation status of 64 species of open ocean (pelagic) sharks and rays reveals that 32 percent are threatened with extinction, primarily due to overfishing, according to the IUCN Shark Specialist Group.
One of the most comprehensive studies ever compiled on illegal shark killing brings new startling statistics. An estimated 100 million sharks are killed every year around the world, a number that far exceeds what many populations need to recover.
The statistical report, compiled by researchers at Dalhousie University in Halifax, Canada, crunched numbers of reported shark catches globally and used data from nearly 100 former papers to estimate the number of unreported shark deaths every year. In a moving range, the researchers were able to calculate that between 6.4% and 7.9% of sharks of all species are killed annually.

An analysis of the flow of shark fins through the Hong Kong fish markets suggests that somewhere between 1.21 - 2.29 million metric tonnes of sharks are killed each year for the fin trade (Lack and Sant, 2009). This means that the biomass of sharks in the fin trade is 3-4 times higher than the FAO statistics. The total number of sharks killed and passing through the fin trade is estimated to be between 26 to 73 million, with and average (median) of 38 million killed each year.
I think it's impossible to give an accurate number seeing that many (most?) sharks that are caught/killed are not reported because it was illegal or not regarded as something to report. Either way - it is horrifying numbers, and so unnecessary.
Shark finning is the practice of slicing off the shark's fins while the shark is still alive and throwing the rest of its body back into the ocean where it can take days to die what must be an agonising death. Some sharks starve to death, others are slowly eaten by other fish, and some drown, because sharks need to keep moving to force water through their gills for oxygen.
Shark finning is the practice of removing the sharks fins after it has been caught in a fishery. The fins are kept and the body of the shark is typically returned to the sea, often while the shark is still alive. Unable to swim or pass water across its gills, the shark dies from suffocation, bloodloss or predation by other species. This is an incredibly improvident practice because 95% of the carcass, a source of protein, is wasted. Only the fins are kept because shark fins are now among the most expensive seafood items in the world with retail values of over US$ 400 per kilogram (Clarke 2004). The value of the shark fin is reportedly 20 to 250 times the value of the meat by weight (Vannucinni 1999). Therefore, it is economically beneficial to use the limited space on a vessel to store a high-priced commodity such as fins than it is to fill it with the low-priced meat of the sharks’ body.

the prices the meat is able to sell for would play a big part in this, why so expensive, Does it make people feel special as they eat it or something. Does it give them a sense of power cos they are eating shark. It just seems dumb and a waste of life to let the shark go only to suffer a slow death.
