Please explain in detail for these two questions. I don't quite understand the concept

1. "Under what conditions is it ethically defensible to outsource production to the developing world where labor costs are lower when such actions also involve laying off long-term employees in the firm's home country?"Please develop your answer based on an ethical theory described in chapter 5 in the text.If you argue that it is ethically defensible to outsource production, describe what should be done for the long-term employees who will be let go in the home country.
2. "Can a company be good at corporate social responsibility but not be sustainability oriented? Is it possible to focus on sustainability but not corporate social responsibility? Based on reading the Focus on Managerial Implications section, discuss how much CSR and sustainability are related and how much the concepts differ from each other." Please describe briefly what you feel is a major ethical dilemma facing a major corporation in the world.Why do you feel it is a major issue?What should the corporation take into consideration as it attempts to confront this dilemma?
