Orcas have been sinking ships off of Spain

[Catherine]

Orcas have sunk 5 ships in 3 years in the area  between Spain and North Africa. No humans have been killed, but ships have been attacked and they have been sunk.

We now know that Orcas can sink ships. We just don't know what has triggered this behavior in one pod of whales.
Maybe they really don't want humans in that part of the ocean. It isn't just young rowdy males. One team of attackers is led by a mature female.
Yes they are probably teaching each other how to do this, but why. Why now?
When you look at how we have treated the oceans, whales in general and Orcas in particular, maybe the question should be why are these the only ones attacking humans and why did they wait so long.
