Reconciling the needs of a growing world population with the resulting impact on our environment is ultimately the most complex and important challenge for society. Sustainable development requires an assessment of the degree to which the natural resources of the planet are both in sufficient quantity and in an accessible state to meet these needs, and to be able to deal with the wastes that we inevitably produce in manipulating these resources (including process and end-of-life waste). We can express this in the form of an equation based on the Earth’s capacity EC, the total population exploiting it P , the consumptive (essentially equating to economic) activity of the average person C , and an appropriate conversion factor between activity and environmental burden B. EC = P × C × B |
