The definition of sustainability is the capacity to endure. In ecology, the word sustainability describes how biological systems remain diverse and productive over time. For humans, it is the potential for long-term maintenance of well-being, which in turn depends on the maintenance of the natural world and natural resources. To achieve sustainable development, the three sectors need to come together. The economic, socio-political, and environmental sectors are all critically important and interdependent. Progress will require technology systems thinking concepts including multidisciplinary and trans-disciplinary research across all three sectors. This proves difficult if major governments fail to support it.
