The statistic that blows my mind is that Alaskan Sea Otters have with in a few years dropped from a population ot 80,000 to 5,000. The best they can tell is it is because Orcas have decided that they should be invited to dinner, when apparently they were not in the past. That is a huge decimation. Far more than were killed in providing pelts to China. Nature can endanger its own species quicker than man apparently.

Now with Great Whites deciding to invite the California Sea Otter to dinner, we have a copycat scenario occuring.

If only we could get Orcas and Great Whites to eat only farm-raised Talapia.

This goes on nonstop in nature. Numerous species go extinct every single day. Or otter populations appear that start out very small but armor plated with poisonous flesh and huge teeth.
As long as we don't screw with it the system has been working fine for millions of years.

Don't forget we are part of the system ourselves, subject to the same principles of natural selection as any other species. For all our success as a species, the planet just reminded us last week how easily that can all change.

Are you saying sharks might be acquiring a taste for people much like
Orcas are acquiring a taste for otters?

That idea may have some merit.

How many humans actually get parts EATEN by sharks?
I think the percentage is extremely small, once the shark senses he made a mistake with his choice of food.

Probably not very many(yet), but if sharks do start eating people, it will likely
enhance their survival, and produce more sharks that eat people.
It's only a mistake in food, if the shark can't digest us to use us for
energy. The system will naturally select the sharks with the broadest
food source. I'm thinking it's only a matter of a few 1000 years before
their fins will get more appendage like, and they start flopping up on
to the beach to pick off our stragglers.

On Maui we are having a high rate of large tiger shark incidents over the last several weeks, no fatalities - just plenty of scares so far. This is unusual to have so many in a short time frame although fall is the time most shark encounters with humans happens - maybe its the ocean eco system destruction

Like robberies here, the shark attacks can be only two or three individuals who soon move on.
The crime wave of forty robberies in Paia area was solved with one arrest.
One single guy did 60% of all crimes against property.
