sustainability(sustainable development) Economic development that takes full account of the environmental consequences of economic activity and is based on the use of resources that can be replaced or renewed and therefore are not depleted. The concept was introduced in the late 1970s and was emphasized strongly in the World Conservation Strategy, published in 1980 by the IUCN in collaboration with the UN Environment Programme and the World Wildlife Fund (now the World Wide Fund for Nature). Our Common Future, published in 1983 by the World Commission on Environment and Development (the Brundtland Commission), defined it as development that ‘seeks to meet the needs and aspirations of the present without compromising the ability to meet those of the future’.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
