Ethics and Economics

I’m working on a environmental science discussion question and need an explanation and answer to help me learn.

For this discussion question I want you to think about one of the following environmental problems: human population growth, climate change, habitat destruction, pollution, or the current health crisis we are experiencing.  Do we have an ethical obligation to address this issue or not?  Please thoroughly explain why or why not using one or more of the ethical standards we discussed in class to justify your actions. 

Whether or not you feel there is an ethical obligation to act, what do you feel is the best way to address the topic you selected? We have discussed both policy and economics, do you think the problem you have selected would be better addressed using regulation or an economic policy?  Explain  you answer.
