Weak sustainability and a post-industrial society

The needs of future as well as those of the present generations are at the heart of sustainable development. Weak sustainability addresses specific concerns for the depletion of exhaustible resources such as minerals. So long as such natural capital is converted into reproducible machines, it is argued that the inevitable time when resources are depleted can be postponed, giving human ingenuity time to resolve the dilemma. But such machines require exhaustible energy to drive them and when they become obsolescent, other exhaustible resources such as iron ore to replace them. Further, with the underdeveloped parts of the world yet to experience the benefits of the industrialised, consumer society, there will be greater rather than lesser consumption of exhaustible resources in succeeding generations. The continuing need for exhaustible resources, therefore, argues against the arrival of a post-industrial society.
