The growth in dive tourism is being blamed for an increase in shark attacks off South Africa according to a report by the BBC.
A spate of attacks has occurred off Cape Town, South Africa. A surfer recently had his leg bitten off, a fisherman was attacked in the past few weeks and a man was killed last year.
Some are blaming dive tourism companies, which provide shark diving trips for holidaymakers, for encouraging the sharks to come closer in than they usually would be feeding them regularly.
Surfer Adrian Charles told the BBC: "Sharks are intelligent creatures and they learn to associate human beings with food.
"They follow the boats into the harbour when in the past they wouldn't come all the way in.
"There are less surfers in the waters now and it's affected businesses like surf shops."
Brian MacFarlane who runs a tour company specialising in dives that allow people to swim alongside sharks such as the Great White, says that it's a coincidence.
Some say surfers are more likely to be hit by lightning than bitten by sharks
"We are not teaching or training the sharks in any way. These incidents are just cases where the sharks mistake humans for other creatures, like seals. It's an unfortunate case of mistaken identity."
