Are we to blame for shark attacks?

Today, I read this piece in the Huff Post. Paul Watson of sea shepherd infamy is explaining in staggering scientific fashion (sharkasm intended), why the number of shark attacks seems to be increasing. Watson is saying:

"Shark attacks are on the rise and the reason for this is entirely the fault of humanity." 

To start with, we are diminishing bio-diversity in the ocean. Overfishing has removed 90% of the fish from the sea since 1950. Every single commercial fishery is in a state of decline. This is not just bad news for humans who eat fish, but it is very bad news for sharks, orcas, whales, seals and dolphins who have no choice but to eat fish. In other words, starvation is a very big motivation for opportunistic attacks.

Hmm, what!? Because there are not enough fish, sharks are attacking humans? Wait, didn't I hear that the seal populations are increasing and GWS as well as Orcas eat seals? 


While I was contemplating on how to disseminate and respond to this stellar piece of fiction writing, I saw that DaShark beat me to it. He is doing it much more eloquently than I ever could here

In his colorful way, DaShark reasons: What a load of horseshit - predator/prey cycles anybody? And are we only decimating the prey - or is it not rather so that we have disproportionally targeted predator populations among which the Sharks? 

The truth is that there is not one single documented case of more Shark attacks occurring because of overfishing!

In fact, when it comes to some GWS populations, we may be experiencing the exact opposite! Having protected the Pinnipeds, we are now seeing more GWS in California, the East Coast of the USA and also Western Australia! And there are authoritative voices claiming that the Tiger Shark population of Hawaii may be increasing owing to the protection of Sea Turtles!

That is only part of his blog. You can read the rest of what he has to say here

Once again, excellent insight DaShark!
