The top right is a nested approach where social and economic sustainability are contained within environmental sustainability. The bottom right shows pillars with the different components holding up sustainability.

Sustainibility (from the Latin sustinere - hold up, hold upright; furnish with means of support; bear, undergo, endure) is the ability to continue over a long period of time. In modern usage it generally refers to a state in which the environment, economy, and society will continue to exist over a long period of time. Many definitions emphasize the environmental dimension. This can include addressing key environmental problems, such as climate change and biodiversity loss. The idea of sustainability can guide decisions at the global, national, organizational, and individual levels. A related concept is that of sustainable development, and the terms are often used to mean the same thing. "Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it."
