    TL;DR nobody knows. It has happened in smaller numbers but not like this. People think over fishing (but a similar event previously in Brazil with no known cause)

      I’m waaaaay out of my waters here, but if I had to take a wild guess: over fishing, changing of chemistry of the oceans do to climate change and yeah rising of median temperature (as we can all feel) of the world … in summary: my guess is human activity.
