CAUSE AND EFFECT ESSAY

       The world today faces many problems despite the fact that it has taken long strides in science, technology and knowledge. One such problem is overpopulation , especially in developing countries. The population is growing so fast. Researchers predict that the population of the world will be 9.1 billions by the year of 2050. Do you know what are the causes for such a growth of the population and the effects of it ?
      The fast growth in population is caused by the high birthrates. Nowadays, with the rapid progress in science and technology, the health services are greatly improved. With the knowledge of science, the sciencetists found a lot of kinds of drugs and the appropriate methods to cure people of many killer diseases. For example, smallpox, a serious infectious diseases, now extremely rare that causes fever, leaves permanent marks on the skin and often causes death has been eradicated from almost countries. Besides lots of killer diseases such as AIDS, cancer... had the special drugs to maintain the life for patients. Thus, while a number of deaths is reduced, there is no control on birth. As a result, the population is increasing at a runaway speed.Moreover, one more reason why the birthrate is too high is that many people desire to have male children. In many countries, it is the pressure of having a boy that causes the birthrate to increase. China is a specific example of this case.Chinese consider that every family should have at least one boy. Because of this way of thinking, in the last few years the birthrate in China set a record speed . However , thanks to one- child family policy that China's birthrate decreased. The uncontroled growth of population leads to the problems of housing and sanitation. In many countries the slums rae a sore to the eyes. Slums grow around the big cities and are found with all the drawbacks. These are the areas of diseases, poverty and crime. Besides, the unemployment is becoming the hot issue which is caused by the overpopulation. Even in such a developed coutry like the  USA, every year the number of unemployees are increasing. Perhaps, the overpopulation is also the burden of the economy.
          Secondly, the illiteracy and the limited access to modern media such as TV, newspaper... are the main causes leading to the growth of population. In some poor countries, people hardly know how to read or write so they do not have knowledge of taking care of their health. In Africa, the women are almost illiterate. They do not know the way to contracept. Most women give birth uncontroledly.  Even there are women who do not know they are having baby until they give birth to a child. Therefore, the growth of population is an inevitable problem in Africa. Furthermore, media such as Tv , newspaper are the most effective way to reduce the growth of population. However, in many countries , the access to modern trchnology is limited. In poor countries, people do not have any TV in their family. They are not educated about family planning  and taking care of their health, especialy women. So the population of the world is increasing every day. As a result, when  every family has about five children , almost children are not gone to school and surely they will grow up in unhealthy living conditions. Children in the remote areas don't even have enough clothes to wear , so how ca they go to school? And the dark of poverty and illiteracy is still covering from this generation to the next one. Besides, the overpopulation affects on our environment seriously. As a result of the growth of population, people destroy the forest to build houses. Now the area of the forests is deceasing. And storms every year that take away the lives of thousands of people are the effects of the overpopulation. If we do not have any solutions to prevent the speed of the growth, in about 50 years human being will face to the shortage of food , clean water and energy.
          Nowadays, people have realized the dangers of overpopulation . Every country is caught up with this problem and population growth control has become an economic necessity.
