Doctors say victim of 6th NC shark attack in two weeks in serious condition
The drive to protect sharks has caused them to become overpopulated, leaving less for them to eat. Thus, they are adjusting by varying their diet.
This reminds me of what happens in the Berkshire and Litchfield hills when deer became overpopulated. However, in the case of Odocoileus virginianus, they did not begin to attack humans, they enabled a growing, and increasingly carnivorous, Eastern coyote population to feed on them. Zoologists project that coyote attacks on humans should become more likely as the coyote population increases over the next decade.
