Humans have profoundly decreased the abundance of both large (e.g., whales) and small (e.g., anchovies) marine fauna. Such declines can generate waves of ecological change that travel both up and down marine food webs and can alter ocean ecosystem functioning. ~ American marine biologist Douglas McCauley et al
The oceans are already undergoing an irreversible mass extinction. It is quite an accomplishment for humanity.
Fundamentally, we’re a terrestrial predator. It’s hard for an ape to drive something in the ocean extinct. ~ Douglas McCauley
Flagrant fouling and overfishing have not been enough. Thanks to advances in marine technology, seabeds are being mined for their minerals. It is a unique opportunity to destroy unknown ecosystems and pollute the deep oceans.
