Changes

The word 'sustainability' has become a wide-ranging term that can be applied to almost every [[facet]] of life on [[Earth]], from a local to a global scale and over various time periods. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. Invisible chemical cycles redistribute water, oxygen, nitrogen and carbon through the world's living and non-living systems, and have sustained life for millions of years. As the earth’s human population has increased, natural ecosystems have declined and changes in the balance of natural cycles has had a negative impact on both humans and other living systems.

There is now abundant scientific [[evidence]] that [[humanity]] is living unsustainably. Returning human use of natural resources to within sustainable limits will require a major collective effort. Since the 1980s, human sustainability has implied the integration of economic, social and environmental spheres to: “meet the needs of the present without compromising the ability of future generations to meet their own needs.”[1] Efforts to live more sustainably can take many forms from reorganising living conditions (e.g., ecovillages, eco-municipalities and sustainable cities), reappraising [[economic]] sectors (green building, sustainable agriculture), or [[work]] practices (sustainable [[architecture]]), using [[science]] to develop new technologies (green technologies, renewable [[energy]]), to adjustments in [[individual]] lifestyles.[http://en.wikipedia.org/wiki/Sustainability]
