Answer:
ethical
Explanation:
The mine is really facing an ethical dilemma since it has to choose from two alternatives that are very bad and no matter what it does, it cannot escape the consequences from deciding one alternative over the other. If it decides to clean all the contamination that it produced, it will go bankrupt and have to close its operations. But if it doesn't clean the water, then many people might get sick from drinking it and that is also extremely bad. There is no good option, and no easy way out.
