Humans have always been very good at killing big animals. Ten thousand years ago, with just some pointed sticks, humans managed to wipe out the woolly mammoth, saber tooth tigers, mastodons and giant vampire bats. The same could happen in the oceans.

We now have the technology to fish down below 2km, something that has been brought in on a large scale in the North Atlantic in the past 15 years.

If you go to any reef around the world, except for those that are really protected, the sharks are gone. Their value is so great that completely harmless sharks, like whale sharks, are killed, for their fins.

I think one reason we got the notoriety for this is just telling people that the oceans are not OK.
