With economic and societal development, the twentieth century witnessed rapid growing in the universe population. Overpopulation has become an pressing job for many states to manage. In Australia, the population has reached about 22 million and the growing rate is twice that of the universe norm degree.
If this high rate continues, it is predicted that by 2050, the population of Australia will transcend 35 million. Presently, it has become a het argument whether the growing of population is a benefit or drawback to Australian life.
This paper argues that the increased population will do more negative effects on a long term footing for three chief grounds. It will add to great force per unit area on the environment and give rise to unsustainable development in the economic system. Furthermore, the high population growing will make assorted societal jobs.
Rapid population growing is a immense challenge to the transporting capacity of the environment. It will do a scarceness of natural resources and impairment of pollution. Australia is a state which abounds in several sorts of natural energy beginnings. It is presently self sufficient in the production of excavation, natural gas and oil.
However, the growing of population will drive up the ingestion of resources. For illustration, the ingestion of coal is increased to bring forth more electricity to fulfill people ‘s activities. At the same clip, big population leads to the limited and unsustainable natural resources divided between more people, which means the per capital sum is reduced.
In add-on, with the betterment of populating criterion, the energy ingestion of each individual has shown a lifting tendency in the recent decennaries. It is predicted to increase at an mean rate of 1.5 % per twelvemonth ( Cuevas-Cubria & A ; Riwoe, 2006 ) .
As a consequence, the growing of population will speed up the exhaustion of natural energy beginnings. For Australia, the deficit of H2O has been a important job for many old ages. In order to back up the population and keep the economic development, 75 % of the H2O use is for irrigated agribusiness.
The day-to-day H2O demand besides shows an upward tendency ( NARN, 2000 ) . Consequently, the increased population will take to the rise of H2O demand, which will decline the H2O scarceness.
In add-on, the exasperation of pollution is another environmental impact brought by the increased population. To turn to the planetary clime alteration, the Australian Government has announced a committedness which promised to cut down the nursery gas emanation 5 % to 15 % by 2020 ( Carrington, 2008 ) .
However, because of the high dependance on energy-intensive industries and the big ownership of private autos, Australian has the universe ‘s highest per capita emanation of nursery gases. If the population continues to increase at a high rate, it is impossible to accomplish this mark ( Birrell & A ; Healy, 2009 ) .
As a consequence, people have to endure from the consequences of the serious air pollution which threaten people ‘s wellness and biodiversity. The population booming and human activities are major grounds of the loss of biodiversityi??Hastwell, 2010i?‰ .
In order to fulfill people ‘s increasing demand of land, H2O and natural resources, many animate beings lost their natural home grounds. Furthermore, because of the influences of deteriorating environment and the clime alteration, a host of species are in hazard of extinction. Therefore, the increased population will give rise to the happening of many environmental jobs.
Furthermore, the growing of population will act upon the sustainable development of the economic system in a long term. To get down with, it will take to the addition of unemployment. It is known that the economic system of Australia to a great extent relies on the energy-intensive industries.
Harmonizing to the informations of 2006-2007, the mineral industry histories for 8 % of Australian ‘s GDP and contribute to the exports and new capital investing for 42 % and 37.9 % , severally ( CSIRO, 2010 ) . The broad rewards and net incomes of those sorts of industries attracted big Numberss of people and investing besides adding the force per unit area to other industries ( Shanahan, 2010 ) .
In a short term the energy industries have capableness of back uping the big population. However, in the long tally, along with the depletion of un-renewable energy, the effects will be the recession of the energy industries and the deficiency of the other industries to back up the increasing population. It will take to the addition of unemployment rate.
Furthermore, the increasing figure of population means that the authorities must increase the investing into substructure to guarantee the public assistance of citizen. Ericson ( 2008 ) states that during the past 11 old ages, in order to avoid the rising prices the Government has non provided adequate substructures to fulfill people ‘s demand.
Furthermore, the substructure evidently aggravates the load of authorities. If the population exceeds the capableness of authorities, it will take to the consequences that the decrease of people ‘s populating criterion.
Additionally, the addition of population leads to the deficit of lodging and the rush of house monetary values. Last twelvemonth there are merely 333 freshly increased houses for every 1000 increased people ( Megalogenis, 2010 ) . The increased population consequences in the demand of houses transcending the supply.
What makes the state of affairs worsen is that, the reasonably loose place buying policy encourages immigrants and international pupils to purchase houses in Australia, non merely for life but besides for investing. It besides drives up the house monetary value.
Harmonizing to the statistics released by Australiai??ABS, 2010i?‰in 2009, the increasing demand for houses has caused an norm of 20 % rush in lodging monetary values in eight major metropoliss of Australia.
As a consequence, it is hard for the mean household to afford their ain place. If the monetary value supports turning, it will likely go the root of other economic and societal jobs. Therefore, commanding the population could turn to the crisis of house monetary value.
Furthermore, the growing of population is an indispensable cause of the series of jobs which affect the societal cloth of society. More precisely, the major metropoliss in NSW, Victoria, Queensland have much higher population growing rate ( ABS, 2010 ) .
The rapid population growing in these metropoliss leads to the house monetary value wholly different from the metropolis Centre and suburbs. The affluent live in the centre of metropolis with high-income and high degree of instruction and wellness attention. In contrast, destitute people who could merely afford the lower house monetary value in the suburbs have comparatively lower populating criterion.
As a consequence, it gives rise to the societal division among people ( Birrell, 2010 ) . At the same clip, the big population denseness of those metropoliss will amplify the extent of lodging and substructure deficit. It will besides add the force per unit area to the transit system.
In add-on, because of the increased demand of houses, people have to travel out from the houses to the flats, which is against their traditional life manner.
An Australian study of societal attitudes shows that 69 % of 3000 Australian electors oppose the population growing and merely 31 % of electors express the credence of the flourishing population ( ABS, 2010 ) .
In add-on, harmonizing to the Australian Bureau of Statistics, ( 2010 ) during the last twelvemonth, there are 500 1000s of people increased in Australia. Among the increased population, 66 % is made up by in-migration and 34 % is natural addition.
The net addition of in-migration leads to the booming of population. Because of the different civilization and background of abroad migrators, they make the society go multicultural and multilingual. But at the same clip, it poses a menace to Australian traditional civilization and linguistic communication and will convey the struggles among assorted civilizations ( Birrell, 2010 ) .
In add-on, a big figure of immigrants come to Australia with low English accomplishment or low instruction degree, every bit good as the increased figure of refugees may give rise to some societal security jobs ( Staff Writer 2010 ) .
Therefore, under the premiss of fulfilling the demand of skilled migration, the Government has enhanced the in-migration criterion to curtail the figure of migrators.
However, some people believe that increased population will excite the economic growing. More revenue enhancement remunerator will increase the authorities gross and economic end product. James Craig, the main economic expert at CommSec, states that more people implies more disbursement and demand for goods and services, which will impel the addition of economic system ( Cole, 2010 ) .
However, this sort of economic growing is a short term net income. If the population still grows at this high rate, it will transcend the transporting capableness of the environment in the hereafter. Therefore, this sort of economic growing is at the disbursal of natural resources and ecological balance.
For illustration, the excavation industry, which has important part to the economic growing of Australia, is booming along with the unrenewable resources ‘ decrease. In order to back up the increased population, Australian economic system can non independently develop without those natural resources intensive industries.
Therefore, a barbarous circle will take topographic point among population, economic system and environment. Taking the pollution produced by increased population into history, this state of affairs will go even worse. As a consequence, in the hereafter more monetary values will be paid for today ‘s over-development.
In decision, based on the statements above, it is obvious that the disadvantage of population growing outweigh the short term benefits it can convey to Australia.
The increased population can speed up the impairment of environment which will straight impact the development of this state. Besides, in footings of a long period, it will blockade the sustainable development of the economic system. Mover, inordinate population will do a host of societal jobs.
Overall, maintaining the balance between the population growing and the whole society advancement is a challenging undertaking for people to turn to desperately.
