Why do sharks have high urea concentrations?

Why do people hate sharks?

• I just can't understand why people hate sharks so much. I kind of blame Jaws for all the fear and hatred of great whites, even if it was based on a true story. But anyway, I can't understand why people have such hatred of sharks. They may have killed hundreds of us, but we as the human species have killed thousands of them. I'm no animal rights activist, but I don't really stand it when people talk about sharks like they're the incarnation of the goddamn Devil because they aren't. They're doing what they've always done to survive and for the record, they were here before humans, dinosaurs, even before insects. I just need to know why sharks deserve such a bad reputation when they're just being themselves.

• Answer:

  youre right in that the media portrayal of sharks is misleading and biased, sharks usually only attack if they mistake a human for a seal or other such prey. there are roughly only 60 shark attacks every year and deaths from these are very rare, especially compared to the 100 million sharks kiled every year for their fins. and there you have your answer, the bottom line is money - the shark finning industry is valued at well over a billion US dollars. some interesting facts are that an american at the beach is nearly 3,500 times more likely to drown than get killed by a shark, and annually more people are killed by toasters than sharks.
