Are there objective and universal morals to which all societies subscribe? If so, how would these morals be shaped by environment, considering that each environment is unique?

Consider the ideas of major ethical philosophers in your response. How might Kant, Socrates, Aristotle or John Stuart Mill answer these questions?
