A crash course in changing the world.
Money are used all around the world. There are a lots of disadvantages of money. First, as time flies the value of the money will be decreased, because the cost of the things that we buy will be increasing. Second, its a waste of paper, and people around the world or country will be touching the money. There will be full of bad germs. Third, long time ago people exchanged something that they want with something that they have, this is called trade. Even the poor people could get what they have wanted, but now they use money and its hard to earn money. The poor people cant afford to make a money and because of that they can't what they need.
One of the major problem about money is the currency, there are a lots of different kinds of currency. People use different money around the world; people use dollar in United State, some use won like Korea, Indonesia use rupiah, yen is used in china, ringit is used in Malaysia. The problem with the currency is that people cannot use that money in other foreign country. For example Rupiah cannot be used as a dollar in United State.
The solution is too get rid of the all the currency, and using one currency.
