Throughout the World different countries experience underpopulation and overpopulation at different times due to the unpredictable and complex practise of migration. Underpopulation occurs when there are far more resources in an country. such as nutrient energy and minerals. than can be used by the people populating at that place. Overpopulation occurs when there are excessively many people and non adequate resources and engineering to back up these people. States such as China and Bangladesh have overpopulation as there are frequently nutrient deficits and deficient energy and mineral resources to back up the population. The increasing globalization in the universe together with the broad and turning spread between the rich and the hapless has seen migration addition over the old ages which means that it is virtually impossible for country to derive an optimal population and keep it. The optimal population of an country is the figure of people which. when working with all the available resources. will bring forth the greatest output of economic return. per capita. which means the highest criterion of life.
Peoples migrate normally migrate from a rural to an urban country due to force and draw factors. Peoples are deterred from life in rural countries as the work is more labour intensive. harvests frequently fail and there are fewer comfortss and services. Peoples are attracted to the metropolis as there is the opportunity of a better paid. less labour intensive occupation. there are more better quality comfortss and there is the opportunity to finally be accommodated in a better quality house. Migration can be such an unpredicatable tendency. which can alter an country sing underpopulation to an country with overpopulation. This is peculiarly the instance with refugees who frequently flee in mass Numberss from wars and struggle in the place state. When mass Numberss of people leave an country this will so see underpopulation. so it is clear that because of migration. peculiarly in LEDC’s it is difficult to maintenance or brace a population in the long term. Both underpopulation and overpopulation can impact a country’s development in negative instead than positive ways.
Bangladesh has a high population denseness of 888 per square kilometer due to a high birth rate and worsening decease rate. This has resulted in 20 % of the population being under the age of 9. The GNP in Bangladesh was 220 dollars in 1992. which is highly low. There is a deficit of industry. services and natural stuffs and the conveyance web is ill developed. There is besides a low degree of literacy due to the limited figure of schools. which has meant that the state has small invention and alternatively has to fall back to overseas. However because of the low capita in Bangladesh it can non afford to purchases endowment which in the long-run would help its economic development.
China is likely the most renown state for it’s overpopulation. China has a population of 1. 211. 21 million life on the mainland. China’s population denseness of 126 people per kilometer. is comparatively high. However. China does non hold the highest population denseness in the universe because of the country’s huge land resources. China is the world’s 3rd largest state in land country ( 5 ) 9. 3 million square kilometer. but the country’s cragged and desert parts do non back up much dwellers. Much of the population is clustered along the Pacific seashore and in several fertile river vales that extend inland. such as the Huang and the Yangtze. With such a huge population. China’s limited natural and economic resources poses a menace to the population. With increased ingestion of resources. the demand for fuel has lead to the devastation of woods. Another job is the ageing population. The per centum of people at 65 or older is 6. 23 per centum. but is expected to make about 17 per centum by 2020.
This alteration has important deductions because most rural elderly have no old-age pensions and must trust on their grownup kids for support. One of the biggest jobs for China is the deficit of land due to overpopulation. A illustration of this state of affairs is the Yangtze River Valley ; a lay waste toing inundation left 3656 people dead and 64 million estates of land drenched. The spread outing population forced lodging undertakings desperate for land to disforest the countries like the Sichuan state in the Yangtze River Valley because the people have nowhere else to travel but the mountains and comeuppances for populating infinite. therefore promoting the eroding which increased the effects of the inundation. Besides. the population is going more urban. The 1990 nose count estimated China’s urban population at 297 million. an addition of about 90 million since 1982. Beijing’s population increased by 17 per centum and Shanghai’s by 13 per centum during this period.
This has lead to tendencies of underpopulation in China as people peculiarly immature work forces migrate to urban countries in hunt of quality occupations. Therefore in rural countries. twosomes with the deficit of labour power or other troubles were allowed to hold a 2nd kid. with a minimal three-year spread between the first and 2nd kid and upon obtaining the necessary governmental blessings. This policy may assist match to cover with a deficiency of labor in the short term but when this extra population migrated to urban countries it will increase the jobs overpopulation is doing.
Another illustration of the jobs caused by the deficiency of population control is the terrible deficiency of H2O in northern China. About 550 million people do non hold adequate H2O on a twenty-four hours to twenty-four hours footing. It was estimated that the deficiency of H2O cost the state $ 35 billion in lost harvests and cut dorsums in industrial production whereas inundations merely caused $ 20 billion in belongings amendss. The Yellow River has been running dry every twelvemonth and it was reported that husbandmans resorted to rending off manhole screens to water their deceasing harvests with sewerage as a last despairing effort. Combined with the deficiency of land and the still-growing population. the deficiency of H2O would decidedly coerce China to depend to a great extent on imported harvests ; this addition in demand could convey about a global addition in grain monetary values.
The deficiency of land and H2O has called for an addition in production in China’s farms in an effort to feed its people. To run into this turning demand. the usage of chemicals in fertilizers and pesticides non merely ruins the quality of the dirt but besides pollutes the imbibing H2O supply. Another type of pollution due to population growing takes the signifier of domestic waste ; a record 1. 42 million dozenss of sewerage was dumped by the metropoliss in 1995.
Although China is sing a monolithic overpopulation job some rural countries are sing jobs due to a deficiency of labor. However a migratory tendency back to the rural countries could spell disaster as the land does non hold the transporting capacity to provide for monolithic populations. The affects a migration to the rural countries would be lay waste toing for the environment. with the devastation of natural ecosystems and over development of resources which could impact the endurance of so many people in the hereafter. In the instance of China migration has non helped to make a balance between under and overpopulation as both rural and urban countries are sing terrible jobs.
Underpopulation is non ever a job though. For illustration Canada had a population of 25 million in the 1980’s and a population denseness of merely 3 people per kilometer. Canada has a GNP of 1920 per capita which is highly high. Canada has developed industries. services. energy supplies. mineral resources and an effectual conveyance web. The high degrees of literacy and national wealth have enabled the state to develop it ain engineering and to import modern inventions. Canada could duplicate it population and still keep a high criterion of life. States like Canada can export their excess nutrient. energy and resources ensuing in more comfortable incomes and higher degrees of engineering. However if their was a greater population within the state devouring these excess resources Canada would go more economically developed as there would be more people to bring forth more money for the state. It has low birth and decease rates. which keep the population comparatively stable.
It is easy to state that if there was a mass migration of people from China into Canada so both states would profit and an optimal population would be created for Canada while China would hold the strain of it population relieved somewhat. However you can’t warrant that this will be the instance. For illustration if the population in Canada did duplicate due to migration so it may go really difficult to conserve Canada’s resources and environment. You can non go through opinion about a possible happening and it affects. as there are so many factors that can change an awaited state of affairs. For illustration if a batch of Chinese people did emigrate to Canada so their different ethical motives and traditions will find the affect they have on an country.
At the minute there is more grounds that migration fails to make a balance but alternatively. there are many instances where population travel from one extreme to the other which create monolithic jobs. Take the state of affairs with refugees. Thousand of refugees have fled Afghanistan following the current struggle. which had given neighbouring states like Pakistan jobs. They can non be expected to merely allow monolithic Numberss of people join a society otherwise there will be terrible direction jobs. As a consequence assistance bureaus and the Pakistan authorities have set up impermanent cantonments to maintain the people close the boundary line.
In the UK there has been underpopulation following the diminution in “smokestack” industries due to the exhaustion of natural stuffs such as coal. Fe. and steel. While these stuffs were being obtained little small towns were ab initio set up to suit the mineworkers. During the clip it took for the resources to go dog-tired the small towns grew. nevertheless the workers found themselves unemployed and had to travel out of the country in hunt of other occupations. The staying population had been “abandoned” and services such as stores and school became creaky bash to the decrease in population. So due to migration the beginning became creaky. as there were no longer sufficient existences to back up the activities within the small towns. The migration down to the south-east has created major underpopulation in countries in Scotland. Wales. the Midlands and the North of England. Such a loss of work force to the south-east has prevented many countries within these parts developing into more comfortable parts.
It is virtually impossible for migration to make a balance between over and under population simple because of the rural to urban migratory tendency in the universe. In most LEDC’s there is virtually no migration from an urban country to a rural country so how can the overpopulated urban countries and underpopulated rural countries of all time equilibrate out. In MEDC’s there is a greater tendency to travel out of the metropolis into rural countries. nevertheless people will non migrate in Numberss to a peculiar country meeting underpopulation. Peoples in MEDC’s have greater control and freedom to take where they migrate to which is why like LEDC’s it is virtually impossible for a optimal population to happen. There is the possible for optimal populations to be created. nevertheless I can non see how these can be obtained without jurisprudence harsh jurisprudence enforcement’s. which would suppress peoples freedom within a state and breech human rights.
