Why has trade become an important element of each economy contemporarily?

Although it can be perceived as a very positive tendency, as there is additional demand for our commodities, we are recommended to also not forget that it also has its negative sides. One of the most influential is referred to the fact that the countries have never been so dependent on each other as they are nowadays. This proves that financial crisis in one country is significantly more influential on situation in other country than ever in the past.
To prove that thesis let’s go return to the year 2007, which is perceived to be the beginning of the economical crisis. The reason why it has started is referred to the fact that the American banks have reduced the safety standards, which led to growing demand on various bank loans. This has ended up in the fact that a lot of money was provided to people, who were unable to pay the rates, which meant that the supply level of estates in USA has reached top level. This led to decrease of their cost and, owing to series of connotations, it has also considerably impacted the topic of trade.
