Sustainable development represents a new paradigm, casting doubt on the belief that development can be based on sporadic and unlimited economic growth thanks to the planet earth’s ability to perpetually provide adequate re-sources to keep pace with it. That belief has been replaced with uncertainty and concern in the face of deteriorating ecosystems, climate and biodiversity, and other risks associated with irreversible changes. Sustainable development is trying to become established for the long term and to sever its ties with any developmental approach that does not take into account the restricted nature of the planet earth’s resources. The implementation of sustainable development has mobilized most na-tional and international organizations and a great number of participants.
