Why those political, sociological, moral, financial, ecological things work out this way now, and together?
Is it because of the population of 6 billion people? Is it because of the economic ideology that puts no stops on nature exploitation and polution? Is it because of "survival" competition to be most selfish, despite most ample total wealth? Is it because things change so fast that ethics and social concerns cannot adopt? Is it because small scale community relations are being destroyed in favour of state-wide economic pumps?
Or to put in other way: How would you predict the moment of a next collapse? By the moment the total population reaches a certain bound? By the scale or tempo of technological progress? Or by the moment when greed gets widely accepted not as a vice but an admirable and decisive virtue?
Last month the price of a dozen eggs in my local grocery store went from 79¢s;/dozen to $1.69/dozen. The answer is H5N1 - Bird Flu. Poultry provided the main source of dietary protein in SE Asia. The destruction of the poultry flocks there, and in China, removed them. The other previously used source of protein was fish but the world fish stocks have plummeted. Thus, SE Asia is turning to American egg factories for a source of protein, greater demand for a limited product drives up the price of eggs in New Mexico.
There is a secondary aspect of this, 50% of the US production of soybeans (soya) went to SE Asia as poultry feed. The previously used duo-crop rotation: corn (zea mays) and soybean, in the MidWestern US has been discontinued and a corn monoculture is being established. Soybeans are a nitrogen fixing plant which reduced fertilizer requirements for the corn and it helped - a little - in breaking the pest and disease cycles.
By going monocrop these farmers are increasing their reliance on oil. As a fuel and as a source of necessarily required agricultural inputs: fertilizers, pesticides, fungacides, & so on from the petro-chemical industry.
Running them, and their customers, into Peak Oil intimating increasing input costs for farmers. At a time when the Supply of corn is growing. The purchase price (Demand) for that corn is dropping. US Midwest farmers are getting less money for growing more corn at a time when their input costs are increasing. Sounds like bankruptcy, don't it?
This could go on, to pick one, with a discussion of how corn is used throughout the food chain which would get into cheap corn being used to feed cattle in huge numbers in limited space, the requirement of feeding antibiotics in their food, drug resistent transfer, and the reduced usefulness of antibiotics for treating human disease.
The only thing I have run across that is more incomprehensible than the US Agricultural policy is water policy in the Southwest. The Agricultural policy does, after hitting yourself over the head with a hammer a couple of times, does have a certain rationality. For a loose definition of "rational." The Southwestern water policy is just insane. It makes no sense. New Mexico ships water to Texas down the Pecos River and the water when it reaches the border of Texas is too salt to use for anything. It's worthless. Yet, every year, we ship water - of which we don't have a lot in New Mexico - to Texas. Who can't use it and won't give it up. The water is shipped due to an agreement signed back in the 1920s - IIRC - based on water flow measurements of, what we now know, was a 500 year flood.
The US Agriculture policy is specifically designed to deliver the maximum amount of beef to the US consumer at the lowest possible cost.
Southwest water policy is a crazy patchwork of Spanish Land grant law, territorial law, greed, Native American treaties, theft, bi-and-multi-state contracts, fraud, self-dealing, idiocy, the US Army Corp (Build We Must) Engineers, various federal goverment projects during the Depression, and a complete inability to cognize the Southwest is a freaking desert. (Desert = Ain't Got No Water.)
Things are only simple if you ignore the complexity and the inter-relationships of how the planet works. Or doesn't. Certainly the baser human emotions such as greed play a role - and so do the nobler emotions. More important is the fact a lot of systems, e.g., Climate, is Chaotic. An itsy-bitsy little tweak in a system can reverberate into a disasterous, from a human POV, shift in how that system does what it does.
She believed in nothing; only her skepticism kept her from being an atheist. -- Jean-Paul Sartre
The Climate (and other Earth systems) are not "itsy-bitsy" sensitive this way - it was stable and conservative through very long times. Even now, with the antropogentic forcing that is anything but "itsy bitsy", the climate is not more chaotic. In fact, the entropy of expectable extreme weather events (both warm and cold, dry and wet, windy and still) is lower (less choetic) rather than higher (more chaotic). I do not really recongize determenistic chaos - rather I see a cybernetic systems which is set out of normal course and now trying to react.
Anyway, we still have to explain why people got this crazy now.
Postive feedback systems destroy themselves. (think of hooking the emitter to the base of a transistor)
Let it be noted as well that some form of positive feedback can be very useful, and is used often in electronic circuits. The circuits don't usually blow up at all. Examples include astable multivibrators and circuits with input hysteresis, such as comparators and Schmitt triggers. These positive feedback arrangements provide useful benefits, such as voltage controlled frequencies for oscillators and noise immunity.
Positive feedback is only 'bad' when one does not want its effects.
In electronics most people are not stupid enough to propose an unlimited growth model. Or rather, the basic model is, sure, for many things, like amplifiers... And it is very, very useful, this model. However, anyone who has ever built a circuit knows that it is indeed bounded, and the region of constant gain/growth is limited... The constant gain model is only useful for a range of inputs... Unfortunately most economists seems to disagree that their discipline, as it is based in the physical world, will have very similar bounds to the constant gain/growth model. They come off a bit like first year electrical engineering students. Confusing the model with the system, and failing to properly take into account how it is premised on limiting the input to a certain range...
In the case of magicicadas, as we learnt the other night, each generation reproduces at the end of its life cycle, and so in that case 1) you can have saturation; 2) you could potentially see chaotic logistic mapping behaviour.
Bush is a symptom, not the disease.
you are the media you consume.
On the subject, all will be well, and if it doesn't at least it'll be interesting.
Most likely something like this: a bit bad-> pretty bad for us, very bad for the global poor-> very interesting-> good for us, as bad as usual for them.
Peak oil is not an energy crisis. It is a liquid fuel crisis.
As for transistor feedback - the easiest way to destroy certain kinds of transistor is thermal runaway. (Oh, the irony.)
And so we get the Mathematical Economics that we get.
Bush is a symptom, not the disease.
Subsytems with expressive functionality put more structure to the whole system - positive feedbacks will be controlled or exploited by "someone", cooperative and competative feedbacks between functional subsystems will gradually occur. Self-preserving functionality of the whole system may emerge.
In the light of this, we should not assume that our destructive growth can physically continue until it crosses boundaries of its own validity - the boundaries may "come" forward themselves. The positive feedback of our run-away civilization should provoke a reaction of the Earth system. Do we see it? Is the explosion of our civilization so unique that the Earth system, even if existing as a smart self-preserving Gaia, "would not know" what to do with it? Or is human impact already so great that an unmistakable stress signal is already received by a core network of geological/atmospheric processes, but the reaction will take some time (a decade or so)?
It's more of a textbook die-off scenario, that - unfortunately for us - is going to be the biggest in history.
Maybe if we're lucky we'll be hit by an asteroid, and we'll be able to blame that instead.
The real problem is that evolution has bred humans to be smart enough to deal with small-scale survivability issues - like 'Whose brain do I eat today?' - but not smart enough to think globally. The predictive horizon of the average human ends at his or her front door. If they're lucky. Thinking far beyond that is too much of a stretch.
And among the humans who are - possibly - smart enough, there's a persistent brain-eating predator class which has no interest in anything except their own immediate pleasure.
We still cannibalise each other economically. And now we've cannibalised most of the planet too.
People can do big scale things, if they have to. But the modern "progress" and conveninece makes things like long-term planning, resourse conservation, child rearing in families unnnecessary. Ideology speeds up the process of unraveling of "obsolete" habits. The canibalism of this scale started recently, and will not last long.
