There’s no mystery about today’s decline? Humans slaughter them at an outrageous pace.

Haven’t humans attributed to mass population reduction for most, if not all, creatures of the ocean?

We treat our oceans like a dumpster.. wonder if that has anything to do with the declining shark population.

Maybe it was caused by the rise of orcas as a predator for many of those species and as competition for food.

Unless these Chinese shark fishing fleets have a time machine I highly doubt the events 19 million years ago help with understanding why its happening today…. we know why.
