The danger of shark attacks is also wildly exaggerated and over-reported. Even people attacked by sharks defend them. The most telling statistic is simply that sharks rarely attack people and even more rarely are those attacks fatal. Despite says/">headlines like "Shark attacks -- and attack fatalities -- up worldwide, expert says," annual fatal attacks haven't hit double digits in the past decade. The International Shark Attack File, affiliated with the Florida Museum of Natural History and considered the authority on worldwide shark attacks, says there were 82 unprovoked attacks worldwide in 2010, 78 in 2011, and 80 in 2012. In 2012, seven of those attacks were fatal (one in the United States), which is up from the average of 4.4 over the past decade, but still an absurdly small risk.
In the U.S. in 2012, rip currents killed about 100, boat accidents killed 651, lightning killed 28, about 3,800 drowned and alcohol killed 88,000. It's also worth noting that by the most conservative estimates, humans kill about 100 million sharks a year, which is doing untold damage to the seas.
