AIR with its value

The key currency is now the "Air" we breath. Starting from gold to note, then pound to dollar, the worldwide currency has chaned. Today, we have something similar to the first key currency used in this world.

All the work to protect the environment resulted in making this money.
Although the U.S. dollar is used in today's key currency, the world seems to be heading for the new currency lead by the EU. This is from the idea that Carbon dioxide emissions trading could develop into a worldwide standard in the near future. I am a little afraid of what the EU is aiming for, which to control the world with itself on the pivot.What I think is that some countries might begin to trade on the security of their own resource. Then what is going to happen is the 21st century version of colonization.

Lack of study makes me write just an imagination with no pursuation...
