We fortify river-banks, and straighten or divert the courses of rivers. In short, by the work of our hands we strive to create a sort of second nature within the world of nature.” Cicero, De Natura Deorum (The Nature of the Gods, c. 45 BC). 9 Mumford (1931).10 Pinchot (1909).11 Hard or strong sustainability implies that renewable resources must not be drawn down faster than they can be renewed – i.e. that (critical) natural capital must not be spent: We must live off the income produced by the capital. Soft or weak sustainability accepts that certain resources can be depleted as long as they can be substituted by others over time. Natural capital can be used up as long as it is converted into manufactured capital of equal value.12 After a heated public argument between Muir and Pinchot among others, the City of San Francisco was authorized by the US Congress to build a dam and reservoir in Hetch Hetchy Valley in 1913.13 “Every individual … neither intends to promote the public interest, nor knows how much he is promoting it … he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of his intention.” Adam Smith, The Wealth Of Nations, Book IV, Chapter II, p. 456, para. 9.14 Ostrom (1990).15 See for instance Dasgupta (2005).16 Finus (2008).
