> When will we learn that if we kill every living thing in the X, we're probably going to regret it later

Never, because it's not true. You haven't convinced me that there's anything wrong with my proposal.

From my perspective your proposal is at least valid. But it's really quite subjective. Personally I've never really cared for the value we put on landmarks and historic sites. Let it become a sunken city and sell submarine tours.

Of course that's my subjective opinion as well.

Maybe it's fine, but why do we assume it's default-fine? All over the world we see things run out of control when we steamroll an ecosystem.

My memory is a bit fuzzy, but I recall there was some news a year or two ago about Norway contemplating the installation of pumps to oxygenate fjords which had stagnated & began to become anoxic due to human activity, and were experiencing toxic blooms.
