Dangerous sharks

Name(s): 
Shark attacks
Incidence 
Most shark attacks along the east coast of the USA are by blacktipped or spinner sharks, no longer than 1.8 metre, which bite and then release, because the human is either too large or does not taste like a fish. Fatalities come when a larger species like a tiger shark strikes.
Claim 
Despite the fact that the number of sharks in the world oceans decreases, with people spending more and more time on beaches the incidence of shark attacks continues to rise.
Counter-claim 
1. Man has gotten the better of this relationship. Sharks kill about 100 people a year worldwide while humans kill about 100 million sharks.

2. Shark populations are actually plunging because of overfishing.
