Scheme of sustainable development: at the confluence of three preoccupations. Clickable.
Sustainable development has been defined as balancing the fulfillment of human needs with the protection of the natural environment so that these needs can be met not only in the present, but in the indefinite future. The term was used by the Brundtland Commission which coined what has become the most often-quoted definition of sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."
The field of sustainable development can be conceptually divided into four general dimensions: social, economic, environmental and institutional. The first three dimensions address key principles of sustainability, while the final dimension addresses key institutional policy and capacity issues.

Natural building involves a range of building systems and materials that place major emphasis on sustainability. Ways of achieving sustainability through natural building focus on durability and the use of minimally-processed, plentiful or renewable resources, as well as those which, while recycled or salvaged, produce healthy living environments and maintain indoor air quality. "Natural building" is a general term with different interpretations by its – mostly – self-directed practitioners.
The basis of natural building is the need to lessen the environmental impact of buildings and other supporting systems, without sacrificing comfort, health or aesthetics. To be more sustainable, natural building uses primarily abundantly-available, renewable, reused or recycled materials. The use of rapidly renewable materials is increasingly a focus. An emphasis on building compactly and minimizing the ecological footprint is common, as are on-site handling of energy acquisition, on-site water capture, alternate sewage treatment and water reuse.
Other concepts, methods and strategies often (or sometimes) associated with natural building include: building "underground," earth sheltering, or berming, "green" or "living" planted roofs, thatched roofs and cement-free earthen floors, rubble-trench, or gabion foundations.

Selected organization
The UN Environment Programme (or UNEP) coordinates United Nations environmental activities, assisting developing countries in implementing environmentally sound policies and encourages sustainable development through sound environmental practices. It was founded as a result of the United Nations Conference on the Human Environment in December 1972 and is headquartered in Gigiri, Nairobi, Kenya. UNEP also has six regional offices and various country offices.
Its activities cover a wide range of issues regarding the atmosphere, marine and terrestrial ecosystems. It has played a significant role in developing international environmental conventions, promoting environmental science and information and illustrating the way those can work in conjunction with policy, working on the development and implementation of policy with national governments and regional institution and working in conjunction with environmental Non-Governmental Organizations (NGOs).
UNEP has been active in funding and implementing environmentally related development projects. UNEP has aided in the development of guidelines and treaties on issues such as the international trade in potentially harmful chemicals, transboundary air pollution, and contamination of international waterways.

All of humanity now has the option to "make it" successfully and sustainably, by virtue of our having minds, discovering principles and being able to employ these principles to do more with less.
