Another ecological economist quotation:

“I think the most basic thing to understand about our global economic system is that it’s a subsystem. The larger system is the biosphere, and the subsystem is the economy. The problem, of course, is that our subsystem, the economy, is geared for growth; it’s all set up to grow, to expand. Whereas the parent system doesn’t grow; it remains the same size.  So, as the economy grows, it displaces, it encroaches upon the biosphere, and this is the fundamental cost of economic growth. You give up what used to be there.”

– Herman Daly (ecological economist)
