Gracie: A First Class stamp 72 hp pill review 2. About money: the financial markets now seem to control the world's economy. The derivatives market is worth 700 trillion US$'s and that is about 5 times the nominal GDP of the whole world. In my opinion "money supply" is overrated. I think of the financial world as the lubrication (engine-oil) that is needed to let the economic engine run smoothly, but the more fundamental driving force (the fuel) should be elsewhere (these über-powerful credit rating agencies would have no idea what I am talking about!). In my opinion, given the 7 billion (US billion!) human beings all wanting to get rich, there will be a fight for basic resources, such as fresh water, food, energy etc. In spite of "globalisation" etc., the world is still divided into nation-states. In my view, it's not only about "sustainability" (given time humans will always find more efficient technology) but more about the speed that humans are changing the natural environment (and that has to do with globalisation)
