"Ecological fallout from economic development is in no way an 'externality' as the economic jargon has it; it is a positive depletion of real wealth, of human and natural capital. To seek to have economy without ecology is to try to manage an environment with no knowledge or concern about how it works in itself -- to try to formulate human laws in abstraction from or ignorance of the laws of nature."
