Trade and travel would be a lot easier with a single， global currency that we all use.
Do you agree or disagree with this statement？ Would a single currency cause any problems？
It is clear to me that the idea of a single global currency is an excellent ideal to work towards. There can be no doubt that trade and travel would be vastly easier. On the other hand I believe that it would cause problems today.
The benefits of a single currency can be seen with the use in Europe of the Euro. Whenever you are travelling between countries using the Euro， the problems of currency changing and exchange rates are history. Similarly business between countries using the Euros is so much easier； no more worrying about exchange rate risk and pricing. Everyone‛s money is the same. The same thing is true with the US dollar. Most countries do not use the US dollar but it is accepted in many places. There are many countries that you can travel to and just take US dollars to use.
At present though a global currency would be impossible. Firstly most countries would not accept the idea. Secondly all countries are in different economic states. Some are economically very strong and some are in a state of collapse with inflation ruining the economy. Such countries could not be brought into a world currency as it would cause massive financial instability worldwide. So it is clear that a global currency would indeed cause some serious problems.
So， in conclusion I see a global currency as a future ideal but it will not happen in my lifetime. It would make trade and travel much easier but the problems it would cause nowadays would be insurmountable.
我很清楚，一个单一的全球货币的想法是一个理想的工作。毫无疑问，贸易和旅游将更加容易。另一方面，我相信它会导致今天的问题。
欧元的使用可以看出欧元的好处。每当你在使用欧元的国家之间旅行时，货币变化和汇率问题都是历史。同样，使用欧元的国家之间的业务要容易得多，没有更多的担心汇率风险和定价。每个人都‛的钱是一样的。同样的事情是真实的美国美元。大多数国家不使用美国的美元，但它被接受在许多地方。有许多国家，你可以旅行，并采取美元使用。
目前，虽然全球货币是不可能的。首先，大多数国家不会接受这个想法。其次所有国家都处于不同的经济状态。一些经济体非常强大，一些国家正处于崩溃状态，通货膨胀破坏了经济。这些国家不可能被带入世界货币，因为它会导致世界范围内大规模的金融不稳定。所以很明显，全球货币确实会引起一些严重的问题。
总之，我认为全球货币是一个未来的理想，但它不会发生在我的一生。这将使贸易和旅游变得更容易，但现在所造成的问题将是不可逾越的。
