Sustainability is a broad concept relating to the maintenance of certain physical and economic systems in such a way that future generations will inherit a set of resources that are capable of providing for their well-being, and the well-being of the ecological communities which form the natural capital of any society. The principle of sustainability includes harvests of certain flow resources in such a manner that the rate of harvest is not greater than the rate of renewal of that resource. This can apply to resources like water, fish, and timber.
