I think we lack the collective will to address the big problems because of our economic systems, and the power given to vast global corporate structures.
We're in the awkward last days of the cowboy round-up and the gold rush.
Political power is in bed with corporate interests, which have very little incentive to change what they do or sell. We would need to restructure some laws. The U.S. would do well to lead that effort, as we remain the biggest (%) 'sinners'. I don't think that can happen as long as Corporations are a person, with the money to buy elections.
Our previous president was an oil man (not very good at it, either) and the V.P. was the top man at a firm that profits from war.
There is an insane money-grab going on now, all over the world.
It's akin to the rush on buying guns in the U.S. We fear the inevitable regulations. We know that the low-hanging fruit is drying up, so, get it while you can rules the day.
There is some truth to what you are saying but i think the bigger issue is the fact we are not living in a utopian Star Trek-like united world but rather a world divided into competing fiefdoms.
This incentivizes the type of scattered policy response we are seeing with some nations recognizing the return on investment in environmental protection that accrues over generations and adjusting their calculae accordingly.
Others are still excluding $$ impacts from their economic analyses and for various reasons related to policy inertia and the protection of established power centers are continuing in a model that most satisfies this particular methodology.
It may not make sense that countries subsidize dirty methods of resource extraction and power generation at the expense of future generations and present-day efficiencies but when you recognize that future generations
just aren't counted, and see the $$ benefits flowing to established centers of power you can recognize the logic behind why they do what they do.
I think that game theory comes into play too as some countries will be competing in the old and new models between themselves, and given the problem is a global one, this will necessarily dilute and slow our policy response and its effectiveness.
I am more and more of the mind that this will take a One World Government to fully realize success, because I can't see all 192 nations independently deciding to align on the proper forward course.
So i have become resigned to a certain apathy and a super long-term view.
If we think about the year 3000, I think they will look at the last few centuries of our present era as the time man set the stage for a bitter lesson with severe impacts that will mark a "forest fire" type moment, where much of us are burned away leaving the remnants to learn the lessons and bring man to a more symbiotic relationship with the environment we live in.
Its time we learn some lessons, and I think those established power centers need to experience drastic pain as a direct result of their activities before anything will really change.
