1. I dont see these two scenarios as future hypotheticals - the question is at what rate will these two current and established, but not mutually exclusive, trends progress.
2. We (Big We as in everyone) need more specifics from China on the H5N1/Bird Flu/Swine Flu/Ebola/SARs virus(virii) that is(are) loose in China:
a1. Was this a deliberate release from a Chinese bioweapons lab?
a2. If it was a release, are the Chinese sending a message/warning much like an underground nuclear test?
b. Or is it a release from a lab due to poor biocontainment protocols?
c. Is a purely natural phenomena?
d. Is China deliberately trying to cull their population (he population on the Planet) to reduce demand constraints on finite resources?
Based on what I read here and eslewhere I would rate probabilities for the above as follows:
a1: 50% likely
a2: 25% likely
b: 40% likely
c: 10% likely
d. 20% likely
Note the above options are not mutualy exclusive.
If these Chinese bugs are gentically engineered - then we have a MUCH Bigger Problem(s), likely requiring a Manhattan/Apollo style project to combat the Outbreaks.
Or we are on the Leading Edge of the Global DIEOFF.
3. Bird Flu in China will IMO increase their demands for fossil fuels - the population currently being hit hardest are rural peasants, not the big city fuel consumers. The Chinese mobilization in response to the outbreaks appears to be massive utilizing all available high tech - read higher fuel consuming - tools.
4. The US and China are on a path of Confrontation over depleting resources. Cost is only one half the problem - the other half of the Peak Oil issue is availability. Higher prices do not create Oil. So sooner or later, I think this leads to major power confrontation - aka War.
My simple wild *ss guess - is that China has elected to cull their population of rural "troublemakers" or if not troublemakers than "potential troublemakers" so that Chinese rural output can be increased and rural demand reduced.
If true - this is the first shot of the next war, but no other nation can do anything about it, because China shot themselves.
As these two trends "heterodyne" I think we can expect in next 5 - 10 years if not sooner:
Wall Street Crash
Massive Unemployement
Most of the world falling into the Failed State status (which is lower than Third World status. Failed States being defined as governements that are unable to provide basic .gov services and maintain a rule of law).
Civil unrest
Border wars
Reduced public health levels
Reduced lifespans for all - elite to poor
Dieoff to levels so that local populations can be sustained based on local resources.
As to surviving the above - I think it is an exercise in statistics and the odds are 5 out of 6 wont make it and that may be optimistic, as the Decline could overshoot on the down side by as much as it has overshot the sustainable carrying capacity on the up side.
50- 100 years from now I think the survivors MIGHT have a chance at creating a sustainable society based on local renewables with some trade.
Any LARGE SCALE switch to renewables now is so extremely difficult to be very unlikely:
1. Investment requires a diversion of existing depleting resources which hastens the depletion and limits the amount of renewables that can be installed in short term.
2. Renewables provide Much, much lower EROEI meaning they are not able to replace fossil fuels at anything approaching current per capita consumption rates.
3. Renewables are diverse and distributed sources of energy - I havent seen any realistic plans for making steel, glass, concrete/cement, pulp/paper, chemicals etc using renewables on a scale that could repalce a substantiual fraction of our current fossil dependent manufacturing.
4. The life expectancy in the USA in the late 1800s was less than 50 y.o; developement of large scale renewables will require a large population of commited and qualified personnel. In a Crunch situation, I expect most will be more focused on localized survival and not on large scale production of renewable energy machines.
5. So the renewable option is not a uniform solution, not one for All, everywhere, but rather is a small limited option for the few that self select themselves pre-Crunch and develop localized and sustainable resources.
