I need to write about Ethics (using some the core principles of Ethics and applying it to something)

The Final Paper is on a topic of the students choice (though it must be cleared with the professor beforehand!) and should be between 6 and 10 pages long(double-spaced, standard margins, etc.).. Based on some of the topics from these books MacIntyre, Alasdair. (1998). A Short History of Ethics, 2nd Edition. Routledge.May, Larry, and Delston, Jill B. (Ed.). (2016). Applied Ethics A Multicultural Approach.6thEdition.  Routledge.Singer, Peter. (1993). Practical Ethics. 2ndEdition(or 3rdEdition, 2007).
