Definition+of+Sustainability

From Wikipedia: 

Healthy [|ecosystems] and environments provide vital resources and processes (known as "[|ecosystem services]"). There are two major ways of managing human impact on ecosystem services. One approach is [|environmental management]; this approach is based largely on information gained from educated professionals in [|earth science], [|environmental science], and [|conservation biology]. Another approach is management of [|consumption] of resources, which is based largely on information gained from educated professionals in [|economics]. Human sustainability interfaces with economics through the voluntary trade consequences of economic activity. Moving towards sustainability is also a social challenge that entails, among other factors, [|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 controlling living conditions (e.g., [|ecovillages], [|eco-municipalities] and [|sustainable cities]), to reappraising work practices (e.g., using [|permaculture], [|green building], [|sustainable agriculture]), or developing new [|technologies] that reduce the consumption of [|resources].
 * Sustainability** is the capacity to endure. For humans, sustainability is the long-term maintenance of responsibility, which has environmental, economic, and social dimensions, and encompasses the concept of [|stewardship], the responsible management of [|resource use]. In [|ecology], sustainability describes how biological systems remain [|diverse] and productive over time, a necessary precondition for the well-being of humans and other [|organisms]. Long-lived and healthy [|wetlands] and [|forests] are examples of sustainable biological systems.
