The money to be made is clearly more important than the extinctions we cause, including our own.
Climate has always changed. It always has and always will. Sea level has always changed. Ice sheets come and go. Life always changes. Extinctions of life are normal. Planet Earth is dynamic and evolving. Climate changes are cyclical and random. Through the eyes of a geologist, I would be really concerned if there were no change to Earth over time. In the light of large rapid natural climate changes, just how much do humans really change climate?
Our biggest challenges for the ocean and for the planet are problems of perception. People need to understand that species extinctions, habitat destruction, ocean acidification, and pollution are all chipping away at the resilience of the thin layer of life that sustains us on Spaceship Earth.
To dismiss the current extinction wave on the grounds that extinctions are normal events is like ignoring a genocidal massacre on the grounds that every human is bound to die at some time anyway.
For thousands of years it has been understood that, just as civilizations have to come to an end, there can even be times of global extinctions. But always there are people who know how to gather the essence of life and hold it safely, protect it and nurture it until the next seeding.
