@Malingermind: I may be biased on this, I should add, being a descendant of Thomas Malthus :)
But yes, getting rid of the mindset of infinite, perpetual growth is absolutely essential as a minimum, both for economic and ecological reasons. I am probably too pessimistic, but I only see violent, revolutionary, ways of implementing any change of this order, evolutionary change seems to be too firmly blocked by entrenched interests who appear to be absolutely blind to anything beyond a 3-month time horizon. Believe me, I really hope I'm wrong about this, because anything like that will be very ugly & still with an indifferent chance of implementing the needed changes.
