http://www.geographyteachingtoday.org.uk/curriculum.making/glossary/environmental-interaction-lotc/

Acceptance of the dynamic interrelationship between physical and human accounts if the world is central to school geography. Making sense of the world is often enhanced by a synthesis of perspectives and understanding across at least three areas of concern

1) Social fairness
2) Economic prosperity
3) Environmental quality

The interaction of these fundamental motivations provides the basis for geographic study of the environment. Thus, geographical perspectives are central to understanding sustainable development.
