Sadly its my personal opinion its only going to get worse.
ITS MY OPINION that the food chain has been interrupted too much and a lack of food for these sharks has seen them moving in closer looking for food.
If you talk to fisherman who fish regularly they will tell you the sharks are more frequent and more aggressive then ever. Shark numbers have been decimated world wide by shark fining so you would expect to see less sharks but many experts (people with marine biology experience and degrees) will tell you numbers are reduced. Some by as much as 45% already world wide.
So why are more sharks being sited. Well smaller sharks have become more a issue as there seem to be fighting for food supplies. This is just my opinion but it makes sense. Fisherman tell that there are no fish left in our waters are they are now traveling further afield to catch fish. So why is it expected that sharks would Be any different. They are looking for food and sadly i think testing more than ever. Hence why it bit his ski and didn't than eat him when he was in the drink.

So in a nut shell what my opinion is that less sharks means more chance of getting hit by one..Its just my opinion though and as Smicko has pointed out I'm not a marine biologist by my theory has been disgusted with many and they all tendered to agree that it could be a plausible theory
