Overfishing and pollution will wipe out most of the remaining ocean fish in the next couple decades if nothing is done about it. We're on track to destroy 99% or more of the species of fish and large animals in our oceans.

Maybe state funding for privateering navies given license to sink illegal fishing boats would be a good start. Trawling and other wildly destructive practices funded by various south asian countries are doing incalculable harm all over the world. Sink on sight is an appropriate policy.

Humanity has to get their shit together, or jellyfish will be all that's left.
