The main idea behind sustainability is to maintain the coexistence of humans and nature on earth and to provide the conditions for the living systems in a safe and productive harmony and to support present and future generations. In line with this idea, beyond the consumption-oriented perspective, sustainability is a holistic approach that aims to put forward economic solutions harmonizing social development and welfare, ecological integrity and social responsibilities. Accordingly, sustainability is described along the lines of three dimensions comprising environmental, social, economic aspects.
