Environmental problems (also outputs) connect with many disciplines such as economics, physical, chemical, biological and so many. In order to analyze and attempt to solve environmental problems, we need to integrate social, natural and other sciences as appropriate. Environmental cum tells us that other disciplines may be taken together to go through analysis and solution.

Thank you
