Excellent thread and from reading the article and when thinking about different organisations seeking to dominate the main populace, I think of the Islamic State which is a group that is hell-bent on dominating the world and killing anyone who opposes it, which has led me to become worried about the possibility of the group rapidly expanding throughout Europe, especially since I live in Ireland which is neutral and has a low population density making it rather weak, and basically enacting a series of killings, destabilising Europe sufficiently to allow for it to expand its caliphate throughout Europe.
That in mind, it seems that the Global superpowers are doing the same and, with the present migrant crisis, we seem to be entering a kind of scenario where we enter the Dark Ages as Europe tries to initiate border controls to keep migrants out, sort of like Rome trying to keep the "barbarians" out with their walls.
I fear that one day, these problems will encapsulate the world in an instant, thus allowing for a mass global genocide. I don't think Climate Change will be the main driver behind the possibility of genocide, but rather, this problem that we have with the economy will certainly cause problems, especially since we are about to crash one day, maybe tomorrow, maybe next week or a year or two, it's hard to say and that's the worst part which makes it impossible for one to even contemplate the current situation.
