Specifically, people who are aware of the imminent collapse should stop acts of denial.
Lets not forget the two $700 billion dollar 'emergency' bank rescue packages of 2008. This was denial to the extreme. This was prop up 'business as usual' at all costs. The powers that be think they did it, they resurrected a doomed economy, the recovery of 2010-2011 is well underway and soon everything will be back to normal.
The truth, of course, is these emergency policies only delayed the day of reckoning. When demand recovers it immediatly hits the celing on oil production, global food limits, et al. We have now used 60 billion barrels of the remaining oil since 2008 and we are further down the depletion curve. When the crisis hits again it will be faster and harder, the proverbial bumpy plateau.
We need serious 'townhall' local efforts to restructure the economy around sustainability. Seriously reduce resource consumption. End growth objectives as primary business and government targets. Begin long term planning to dike essential cities like New York, Boston, Vancouver, and London from rising sea levels 50-100 years on.
Rethink how the economy functions with the knowledge that if you have 30% unemployment you get revolution. Jobs, or at least incomes have to be guaranteed to some basic minimum in preparation for economic downsizing.
Is any of this happening? Not even remotely. Instead we have make believe 'Earth hours', spend our time re-engineering laundry soap to be used in cold water and spend millions in advertising to get people to buy it (Jevons paradox in action), divert staple food crops for automobile use, ect, et al.
So Ludi now that I've answered, what do you call the collective stupidity of the masses?
