Along with so many others around the world, my heart goes out to the  people of Japan as they face an ongoing tragedy brought about by a  devastating earthquake, followed by a tsunami, and subsequently a  worsening nuclear disaster.  When such horrible things happen to such a  sophisticated and cultured society, it reminds us all of our tenuous  position on this Earth.
I do not at all want to minimize the trials and tribulations of others  around the world who have also been confronted with horrible disasters  in recent years -- Haiti, Indonesia, New Orleans, and Iraq come to mind  -- but as the third largest economy in the world, and as a technological  powerhouse, what's happened in Japan is a reminder that any of us can be devastated at any time.   The most advanced engineering can't prevent tragedy, and the most  advanced technologies can prove to be the most dangerous.
And it needs to be pointed out that, given Japan's geopolitical & economic  status, the tragedy in Japan may prove to bring about crisis around the  world.  The effects may not be as sudden or shocking as the earthquake  which the Japanese people experienced, but the economic ramifications  could be equally as tragic for many people across the globe.  It feels a  little callous to talk of dips to the GDP and the crash of the Nikkei  stock market, but international trade has been effected -- and in this  interconnected global economy, people's very lives depend on certain  aspects of trade.  How the terrible events in Japan will effect people  in other nations remains to be seen -- but have no doubt that people  will be effected in ways precisely unknown at the moment.
In the simplest of terms... consumer-based economies of the west (like  the United States) will almost certainly be effected.  Production in  Japan has largely been halted, supply chains have been disrupted, and  the types of imports into the world's 3rd largest economy will be  substantially different.  All these factors will reverberate throughout  the factories, fields, and mines of other nations.  Unemployment and  economic hardship are almost certain to follow -- and those hardships  will cost lives and destroy nations.
Don't mistake me for believing that up until now there has been economic  justice or stability around the world!  On the contrary!  But that's  what makes the situation even more dire.  Those in power, particular the  corporate oligarchs, are likely to exploit this disaster just as they  have so many others.  Undoubtedly, we will soon be seeing yet another  example of "The Shock Doctrine" put into practice.  In the wake of a  disaster of this magnitude... it is impossible to speculate upon the  depths of depravity to which the corporate fascists will stoop.  Our safest  bet would be to not underestimate them while preparing to resist.
Furthermore, in light of the global economic chaos of recent years, the  recent events in Japan may prove to be the linchpin which unravels the  entire global economy.  Accusations of histrionics may fly, but never  have there been so many people dependent upon the machinations of such a  corrupt and cruel global economy.  Never before has their been such a  disparity of wealth around the globe.  Never before has their been such  tight demand on a non-renewable fuel source.  And as tenuous and  contrived as the whole modern economic system has become... it's just  taken yet another terribly devastating blow.
A reiterating word must be said regarding the tight demands of fuel for  the global economy.  In particular... the peaking of non-renewable coal  and oil.  The reality of peak oil is actually a very simple concept, but  few have adequately acknowledged it.  As the human population is  growing exponentially...  the primary fuel of our modern  techno-industrial civilization is simply running out.  If extraction  rates haven't already peaked -- as many experts have suggested -- they  certainly will in the not-so-distant future.  We are talking about the  fuel which powers the tractors, transports the food, and forms the  primary basis for petro-chemical fertilizers and pesticides.  Simply  put... the whole system of modern agriculture practices is  unsustainable!
The concept of peak oil is not brought up merely because it plays such  an important role in the global economy.  It is a problem all on its  own, to be sure, but when such individual problems are put into the  context of other serious economic problems... it becomes apparent how  they are interconnected.  And what this current article is suggesting is  that Japan is very much connected with the rest of the world's  economy.  A crisis like the one we are seeing in Japan will have  repercussions throughout every other sector -- all around the world.
Finally, a word needs to be said about nuclear power.  From the first  tests of nuclear weapons, to the bombing of Hiroshima; from the meltdown  of Chernobyl to toxic waste, and on to the proliferation of  fissile material... nuclear power has never been the safest or cleanest  technology.  Many people around the world have been sold its merits by  governments which actually had little interest in it beyond its utility  for war and profits.  But it's never truly been a viable long term  solution to the world's energy needs.  In any case, either way, the prospects  for expanding nuclear power around the world have undoubtedly been  diminished as the world witnesses the ongoing meltdown of reactors in  northern Japan.
And again, the nuclear tragedy in Japan is also the world's crisis.   Japanese people are known around the world as being at the forefront of  technological advancement -- and if their nuclear power plants can melt  down... it could happen anywhere.  Indeed, many lesser reactors are  currently in operation around the world.  All of them need to be  formally, efficiently, and quickly decommissioned.  And while that may  sound like an extreme proposal... it would be nothing compared to more  nuclear disasters.        
No further proposals will be made in this article beyond that last one.   The crisis in Japan is a microcosm of what we are all facing everywhere  around the world and, at the very least, we are all effected by the  events taking place in Japan.  The reality is... civilization is in  dangerous and uncharted waters.  Some might suggest that these things  have always happened in every civilization, but never have we (as a  species) experienced problems of this magnitude -- with so many billions  of us dependent on such a corrupt, flawed, and faltering system.  If we  do not acknowledge and actually rectify the myriad of problems with our  modern lifestyles... I am not sure what can save us from ourselves.
