You are sure that you have heard the word “Ecology“. You know this word is flooded with clipped form “Eco” in this age. My professor indicated that on his blog. The word “Ecology” changed its meanings significantly. In the now, it mean hardly a academic field but one of the service, a kind of what is consumed. From this fact, I think that the capitalism which can’t develop economic without consumption don’t seem to have a power to accomplish sustainable development.
