In the reading for this week, Onora O'Neill suggests, "Most of us agree that we should value the environment, or at least some bits of the environment; fewer of us agree why we should do so.

How can we define environmental ethics in the contemporary moment? 2. What are the factors involved in creating an ethical scaffold for understanding the natural world and its resources? 3. What is the role of duty and obligation?
