Sadly, no. There are historic levels of fisheries failures. We are seeing more activity because whales etc. have not found food in their customary hunting grounds and are congregating where there’s still food..until it’s depleted.
Unusual amounts of emaciated (no food?) grey whales washing up on beaches, salmon fisheries crashes, reports of seal reproduction dives ...not good.
Actually what I’ve seen is poisoning from red tide. We’ve had sea lions on shore sick but it’s been neuron toxins from red tide.
