This course was very instructive for me. Some of the materials I studied in this course impacted considerably my view on environmental protection. I learned in this course how our old ideal of economic system is now one of our biggest threats. So, a new conception of economic agents behavior and system is urging to save human being. In others words we should be aware that more is not better as we were thinking all the time in economics. For instance, The Nobel Prize-winning economist Joseph Stiglitz demonstrated us that the GDP is not the best measurement of the national economic success.
