Well, if humans stopped ripping out more than 500.00 tonnes (and rapidly growing) of Krill every year, there would be a lot more to go around.

My point is you can't have your Krill and eat it too.

Any details? Which "pelagic sea birds"? Which "whales"? Species? Numbers? Rather than a terribly superficial statement?

Very unlikely scenario.
Rather than negative climate impacts or human fishing scenarios causing an 80% decline of Krill, it is more likely that the massive expansion of whale populations are depleting the Krill biomass. We are observing pelagic sea bird declines and there is a correlation where whale populations are increasing.
