pg. 101 The very idea of "consumer" is a big handicap to thinking straight - err, I mean thinking circularly. The word falsely conveys that what we purchase disappears from the ecosystem. But actually, we consme nothing at all. There is no “away” to which we can throw our stuff. That’s the heart of what the ecological awakening teaches us.
More accurate terms are "buyer", "purchaser, or "user". Using them we’re reminded that we are simply a pass-through in a conversion process. Our “stuff” moves from extraction and processing to another state - and that state is either destructive pollution or re-use and, ultimately, healthful integration back into the wider ecosystem.

In fact, we have no choice about whether to be world changers. If we accept ecology’s insights that we exist in densely woven networks, then we also must accept that every choice we make sends out ripples, even if we’re not consciously choosing. So the choice we have is not whether, but only how, we change the world.
