Picture this: you set up a long trail of dominoes that contains around two hundred of the spotted rectangles. Lightly tap the first and watch the effect. One small bump causes all of the following dominoes to topple over. In this example the dominoes represent the economies of every country world-wide, and your finger represents an economic crash. As you can see, every country has some effect on the others. The effect can be as big as a close trading partner, because you may be expecting goods, or as small as expecting a large group of tourists, because you may need the money that the group brings. Because But all of the countries are interlinked.
Just lately, the countries of North America and Europe have entered a time that many call an economic meltdown or crash. The values of their currencies have rapidly depleted and their businesses are losing money which has caused the majority of the businesses to lay off their workers resulting in rising unemployment rates. The stock markets have plummeted in a downward spiral causing millions of people to lose money. Prices have skyrocketed on necessary items and people are losing the shelter above their heads because they don't have the money to pay their bills. But to sum it all up our global economy is falling to extremes that it has never reached before. The only thing left for us to do is rebuild.
