The main objective of Rio was to demonstrate how sustainable development issues could be integrated into planning and implementation. To do this, and help guide countries in the process, a 40 chapter 800 page Agenda 21 document was developed and adopted. This is a non-binding document, which showing how sustainable approaches can be built into all facets of life, all sectors of society, at all levels, for all habitats and ecosystems and be part of all current and important issues and challenges. It essentially called for a paradigm shift - a new way of approaching and managing things, one in which money issues, people issues and ecological issues are all carefully considered with their mutual long-term best interests in mind.
