Annotation

At first ,I need to give a particular account of the Prisoner's dilemma.

According to colummn, two prisoners accused of the same crime find themselves in separate cells, unable to communicate.
Their jailers try to persuade them to implicate one another. If neither goes along with the guards, they will both receive a sentence of just one year.
If one accepts the deal and the other keeps quiet, then the turncoat goes free while the patsy gets ten years.
And if they both denounce one another, they both get five years.

If the first prisoner is planning to keep quiet, then the second has an incentive to denounce him, and so get off scot-free rather than spend a year in prison.
If the first prisoner were planning to betray the second, then the second would still be better off pointing the finger, and so receive a five-year sentence instead of a ten-year one.
In other words, a rational, self-interested person would always betray his fellow prisoner.
Yet that leaves them both mouldering in jail for five years, when they could have cut their sentences to a year if they had both kept quiet.

That situation is called "prisoner's dilemma".

So This game have been playing by all countries on the earth.
The game must be one of the causes to break Kyoto Protocol.

My Thoughts

・According to this colummn, economic-powers like America don't care climate changes. It's not only America but also Japan and some Europe countries. for example, these days, I have interest in Emissions Trading. The Emissions trading is is an administrative approach used to control pollution by providing economic incentives for achieving reductions in the emissions of pollutants.If rich countries or companies bought the right to exhaust CO2, They can exhaust a lot of CO2 without panishment.
I think this emissions trading must be escape route to break Kyoto Protocol.
Sadly, Many Japanese countries also have been buying the emissions trading right recently.
I don't know why Most of goverments allow the emissions trading.
Surely, All countries want to be rich country without caring climate changes.
That situation is just "prisoner's dilemma" on the earth.
But actually, Most of countries have interest in climate changes. They also know this game is not good for our earth.
So The ecology technology will get into the limelight with this game. The ecology technology business will be successful while this game is continue.
If I thought so, I could understand why Toyoto hy-brid technology is such a popular over the world.
