If the island is privately owned then hard to see how "future generations" will be able to study and enjoy it. Maybe, but probably not, eh? That's the point of it being privately owned. Now if the State of Hawaii were to assert eminent domain, acquire it at fair market value, and then turn it into public park lands as designated wilderness, well that might work for your intent, I think.
The island is owned by the natives. And it's still a tragedy to the entire world if they decide to put skyscrapers on it. It's the last bit of untouched wilderness in a unique ecosystem.
This story doesn't make a case for not telling people what to do. It makes a case for not trusting natives to protect the wilderness.
Or maybe not. I don't have context. I am asking a question.
