What is sustainability? Sustainability is about maintaining the capacity of the environment to support our lives and those of other living creatures. Sustainability considers the interconnection between the human and the natural world, and who gets which resources and where. It involves the use of resources in a responsible way that doesn’t exhaust them for future generations. What is scale? When we examine geographical questions at different spatial levels, we are using the concept of scale to ýnd more complete answers. Scale can be applied from local, regional, national or global levels. Looking at things at a range of scales allows a deeper understanding of geographical issues. Different factors can be involved in explaining phenomena at different scales. Local events can have global outcomes; for example, removing areas of forest at a local scale can have an impact on climate at a global scale. A policy at a national scale, such as forest protection, can have an impact at a local scale, such as the protection of an endangered species.
