ABSTRACT
The Brundtland Report, Our Common Future, described sustainable development like this: "development that meets the needs of the present without compromising the ability of future generations to meet their own needs''. The report said that meeting the needs of the world's poor should be a priority, adding that doing this was difficult because of the lack of appropriate social organisation and technology. Sustainable development is not really about the environment; rather, it's about our capacity to change how we live so that we don't upset the delicate balance between ourselves and the biosphere. In 2012, Kate Raworth, working with Oxfam, captured this idea in a striking fashion, with a way of thinking about sustainable development that is completely different from the way that classical economics sees it. It combines the concepts of planetary boundaries and social ones. The atmospheric boundary is physical in nature, and it embodies real limits.
