The cause and effect of migration

Every year, large numbers of people migrate from one country to another for various reasons. Many of them are willing to abandon their careers and homes in own countries and start a totally different life in a new place. However, the great flow of immigration has brought some effects to both the sending country and host country.This essay will briefly review the cause of human migration and some effects on the different types of countries.

There are many reasons to explain the migration phenomenon. Taken together, most of them can be divided into two parts--pull factors and push factors.（from Natasha C. Parkins) The pull factors are aspects that attract people to a new country.For example, the change of concepts makes people realize the real importance of life.Many people shift their sight from making money to getting a healthy and free life. Most wealthy people from some developing countries start to seek for a new society with fresh air, beautiful scenery and peaceful atmosphere. That is to say, excellent surroundings, as a pull factor, plays a vital role in the reason for migration. In addition,well-paid job opportunities are also attracting those people who are eager for creating a fulfilling life to their families. The push factors are conditions that drive people away from their countries. For instance, some countries focus too much on the development of industry and economic which made the environment become seriously polluted. This factor has pushed the native who has the ability to emigrant to a clean country for the consideration of health.

The reasons of migration can be understood by all of us. However, it has caused some effects to both sending country and host country.

The results of immigration can be divided as following. Immigration depletes a country`s intellectual capital and energy. As we know, most immigrants are the well-educated group in their countries. However, they bring their knowledge and wealth to another country which exactly undermines their own countries` benefit. For example, some intellectual scientists in China migrated to the United States for further study. As their new identities-American citizens, they got the Nobel Prize for the US after hard working. As a matter of fact, the outflow of talent made China have nobody to win the Nobel Prize in the science field even though some foreign citizens of Chinese origin had won it. The migration has also brought large amounts of influence to the host country. Firstly, the excessive labor force made the competition of jobs become more fierce. Secondly,the security of the host country faces an acid test because of the superabundant immigration. Last but not the least, the burden of government in the host country has increased rapidly.

To sum up, the effects of migration mainly include pull factors and push factors. The major pull factors are the opportunities of seeking jobs and the wonderful pursuits of human beings who want to lead a fulfilling life. The primary push factors are the poor conditions of the environment and some limited policies of their own countries. Furthermore, migration also brings some effects to the both types of countries. It made the sending country lack labor force and intellectual talents and it also made the host country rise in population which even threatens the national security.
