Permaculture 'guru' David Holmgren wrote in 2008 about 4 future scenarios because of climate change and peak oil.
He has now adapted his writings http://simplicityinstitute.org/wp-content/uploads/2011/04/CrashOnDemandSimplicityInstitute13c.pdf
Nocole Voss has also responded to it here: http://permaculturenews.org/2014/01/17/crash-on-demand-a-response-to-david-holmgren/
Essentially my understanding is that a global financial crisis can be a blessing in disguise as an end to many wrongs in the present global financial system. People that are living frugally and grow their own and are in a community such as here, will more than likely survive. david calls for ways in which this can be sped up.
Whatever your beliefs on it, it is good food for thought! I thought I'd share.
