Well, it's a stupid excuse, but it sort of kind of makes sense, doesn't it, because you'd think that whales eat huge amounts of fish and krill, so obviously take the whales away, there'll be more fish and krill.
To głupia wymówka, ale wydaje się sensowna, bo skoro wieloryby jedzą dużo ryb i kryla, to oczywiście po zabraniu wielorybów będzie więcej ryb i kryla.
