It is impossible to separate economic development issues from environment issues. In its most practical aspect, sustainability is about understanding the interconnections among environment, society, and economy. This book aims to provide a comprehensive overview of current theories and approaches in the area of engaged sustainability for academics, researchers and practitioners. Specifically, it will focus on making responsible decisions that will reduce humanity’s negative impact on the environment. While various social and political initiatives for sustainability are welcome, one cannot really enact sustainability into legislative laws. Something has to change fundamentally at the level of a common person in the street.
