Environmental Chemistry Education for a Sustainable World: What should it take?

In view of the unrealistic and/or unfulfillable expectations of people in our world of conflicting/competing values, interests and finite unevenly distributed resources, the environmental imperatives and the limited economical feasibility of many of even the most innovative/advanced technologies, the emerging battle cry of all to "think globally and act locally" towards a sustainable world, - via sustainable development, - is obvious. Yet, although science and technology may be useful in establishing what can be done in this respect, neither of them can tell us what should be done, particularly with respect to sustainable development, which is conceptualised differently by different people, groups and societies.
