Sustainability
From Wikipedia, the free encyclopedia
Sustainability is the capacity to endure. In ecology the word describes how biological systems remain diverse and productive over time. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. For humans, sustainability is the potential for long-term maintenance of well being, which has environmental, economic, and social dimensions. Healthy ecosystems and environments provide vital goods and services to humans and other organisms. There are two major ways of reducing negative human impact and enhancing ecosystem services and the first of these is environmental management. This approach is based largely on information gained from earth science, environmental science and conservation biology. The second approach is management of human consumption of resources, which is based largely on information gained from economics. Sustainability interfaces with economics through the social and ecological consequences of economic activity. Sustainability economics involves ecological economics where social, cultural, health-related and monetary/financial aspects are integrated. Moving towards sustainability is also a social challenge that entails international and national law, urban planning and transport, local and individual lifestyles and ethical consumerism. Ways of living more sustainably can take many forms from reorganising living conditions (e.g., ecovillages, eco-municipalities and sustainable cities), reappraising economic sectors (permaculture, green building, sustainable agriculture), or work practices (sustainable architecture), using science to develop new technologies (green technologies, renewable energy and sustainable Fission and Fusion power), to adjustments in individual lifestyles that conserve natural resources.

The word sustainability is derived from the Latin sustinere (tenere, to hold; sus, up. Dictionaries provide more than ten meanings for sustain, the main ones being to “maintain", "support", or "endure”.[3][4] However, since the 1980s sustainability has been used more in the sense of human sustainability on planet Earth and this has resulted in the most widely quoted definition of sustainability as a part of the concept sustainable development, that of the Brundtland Commission of the United Nations on March 20, 1987: “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”[5][6] At the 2005 World Summit on Social Development it was noted that this requires the reconciliation of environmental, social equity and economic demands - the "three pillars" of sustainability or (the 3 Es).[7] This view has been expressed as an illustration using three overlapping ellipses indicating that the three pillars of sustainability are not mutually exclusive and can be mutually reinforcing.[8] The three pillars have served as a common ground for numerous sustainability standards and certification systems in recent years, in particular in the food industry.[9][10] Standards which today explicitly refer to the triple bottom line include Rainforest Alliance, Fairtrade and UTZ Certified.[11][12] The triple bottom line is also recognized by the ISEAL Alliance - the global association for social and environmental standards. Sustainable development as defined by the UN is not universally accepted and has undergone various interpretations.[13][14][15] What sustainability is, what its goals should be, and how these goals are to be achieved are all open to interpretation.[16] For many environmentalists 'sustainable development' is an oxymoron - as development seems to entail environmental degradation.[17] Ecological economist Herman Daly has asked, "what use is a sawmill without a forest?"[18] From this perspective, the economy is a subsystem of human society, which is itself a subsystem of the biosphere, and a gain in one sector...
