Sustainability, as defined by the United Nations, is the ability to meet the needs of the present without compromising the ability of future generations to meet their own. It essentially means using resources responsibly so they don't run out and can be maintained for a long time. This concept is also about finding a balance between the environment, the economy, and social equity.
