Your proposal is to do nothing and then make sure the entire thing causes orders of magnitude greater costs and damage which can be irreparable for centuries.
That has ALREADY been tried, and it was an absolute disaster, killing people, wrecking lives, and wrecking vast areas of ecosystems including driving species to extinction.

It is far worse for everyone to let them cause irreparable damage then hit the company/investors with crushing legal actions after the fact.
