It isn't going to be as bad as starving in a medieval wasteland. It will, however, be bad.Darth Wong wrote:Don't the more apocalyptic "Road Warrior"-style scenarios require that the drop-off in oil availability be precipitous? Why won't oil get more rare and expensive over a period of 20 years, thus allowing time for people to adjust? Some of these scenarios seem to assume that it happens virtually overnight, like people are happily filling up their SUVs on Monday and starving in a medieval wasteland by Friday.
Valdemar already answered the why of how this can go.
For the best example of what it may resemble, I suggest Red Victory: A History of the Russian Civil War -- Or, as the blurb puts it "Battles, epidemics, mass starvation and executions afflicted the Soviet Union from 1918-1921 during the Red Army's clash with the anti-communist Whites."
Society won't break down totally like in Mad Max. Technological civilization won't end. It will simply suffer immensely, and go through the kinds of chaotic extremes which have only been see a very few times by a modern society, one of them being Russia in the 1918 - 1921 period (and rather longer afterward, if we want to be technical).
The best way to imagine it--the governments will function, some factories will continue to operate, the armies will still be intact--but thousands of people will be die in the major cities every week, who knows how many will simply vanish of epidemic and famine elsewhere, and it will simply be ignored. As there was nothing that the leadership could do even if they cared. In trying to implement solutions, they will fight wars, which will kill even more people. Because the only way to implement solutions will be authoritarianism, opposition will spread and civil wars can easily start, in which millions more people will be killed by the disruption they cause, mass executions, concentration camps, etc.
By the time it's done in any particular country, industry will be set back 30 or 40 years, millions or tens of millions of people will be dead, society will have massive sociological scarring from the events which will last for a long, long time; there will probably be authoritarian governments in power; and there will be a legacy of concentration camps, forced labour on a truly immense scale (rivalling the Nazis and Gulags, easily, as we'll simply need to do it to get things done in the described environment), and summary execution of political opponents for the survivors to deal with.
That is what the worst case scenario looks like.
Can we avoid it? Yes.
But right now we're not doing anything to avoid it, so it'll happen by default.
And time is running out.
