Systemic change, but to what? What is the methodology that allows us efficiency, and solidarity, intelligent decision making which takes into account ALL perspectives? A methodology which allows us coherent practices that require sensitivity from though the micro to macro. 

Having lived on blockades from Australia to BC, and hung out with primitivists for months on end, I can say that primitivism or ending all industrial output is not exactly the answer. That's not a system, for example we can't just shut down all of industrial agriculture and not get the same result we're looking to avoid, billions starving to death. 

More likely, how can we transition a whole global industry - ecosystems , which in good regions can feed other regions that are facing desertification or disaster this year or next, and while destroyed regions put in swail and moisture capture, and build up to zone 3 then zone 6 forests, and so on to feed themselves? 

Participatory economics (parecon) is (unfortunately) the only complete human systems methodology proposed so far. Fortunately however, parecon is seemingly quite elegant as per hundreds of us trying to poke holes in it over the past 2 decades. Check it out.http://www.zcommunications.org/topics/parecon
