Human Population Growth And Its Effect Environmental Sciences Essay

Population bud can be defined as an extension or reduce in the population enlightenedness of stay estimation including ethnical men-folks. Ethnical populations are too theme to normal arrangement of fount and decease. There has been a flying extension in the universes ethnical population poise the ultimate few decades (UNFPA, 2011). True imperative steps are smitten to restrain population, earnest wholes can initiate love environment hurt and scant availability of prop instrument. Continuous population bud can be whole and accordingly it is relevant to know how we can husband population bud for the boon of all.

Ethnical men-folks possess mellow to compel prop instrument suited for all the population in frequent ways. Starting from the industrial deflection, advances in confer-upon salve, and unpractised farming deflection possess all made us headstrong tit so far. So-far such technology bud cannot go constantly and accordingly true we husband population a day may end when all instrument allure be artistic.

At confer-upon there are two discipline of conception for the theories on population bud.

The principal is the pessimistic purdumbfounder patent clear by Reverend Robert Malthus, a British savant who admired that the instrument suited allure not be tit for ethnical men-folks if ethnical population is not restrainled. The other hypothesis is the optimistic purdumbfounder patent clear by Julian Simon who admired that ethnicals can husband the manifestation of population consequently of their notice and skills. Accordingly this essay allure examine these two theories for population bud and their commodities on the instrument and environment of the sphere.

II. Factors forcible population bud

The population bud is decided enlightenedly by fount scold, decease scold, and locomotion patterns (imlocomotion and colonization). For prompting the population in the patent clear countries love Europe and America is growing at scold of barely 0.1% per year opportunity in developing countries the bud scold is poise 1.5% per year. (Wright and Boorse,2011) (UNDP).

In developing countries where manual labour is tranquil considered deep fount of labour, offspring construct part-among-among of the labour vigor and accordingly families atatco-opeblame to possess aggravate offspring. Similarly when the pension method is not good-natured-natured, persons atatco-opeblame to erect aggravate offspring to contemplate subjoined during old age. Wherever women are aggravate educated and obtain?} bring role in intimate inend activities, there atatco-opeblame to be end sum of offspring erectd. In areas where traditions, anthropologicalization and subsidy are respected population atatco-opeblame to be conspicuous due to end use of contraceptives.

III. Impacts of population bud

Although it may be troublesome to estimate the carrying compatability for ethnicals on sphere (Cohen, 1995) scientists possess estimated the carrying compatability at encircling 7.7 billion persons (Van Den Bergh and Rietveld, 2004). It is now estimated that the universe population allure be encircling 9.1 billion by the year 2050. The very eminent population bud has erectd concerns that the planet may not be consequenceual to stay such population in the covet run. Increasing population allure moderation extensiond claim for prop, infiltrate, and other instrument such as fossil fuel. The collision of population bud can be seen by entireone who regard for the universe that we speed in. Poise the ultimate few decades there has been enlightened lamina perdition of the typical forests enlightenedly to compel place suited for farming and for urbanization. In prescribe to development plenty prop to coalesce the claim of growing population, forests possess been cleared to underobtain?} farming. Due to extensiond industrialization and urbanization, there has been wide extension in the stain of air, infiltblame and the environment of the planet. Growing population allure development in the depletion of normal instrument such as infiltrate, fossil fuels (Hubert, 1982); deforestation and waste of ecosystems; and emergence of new indispositions. It allure too bring to aggravate languishment, hunger and unhygienic stay conditions in penniless countries.

IV. Factors forcible environment

Environment moderations our dressing in which all the things, stay or non stay, which includes sphere (air), hydrosphere (water), lithosphere (substantial sphere), biosphere (all stay organisms), and geosphere (rocks and regoliths). Numerous deedors desire our environment which includes anthropogenic activities such as urbanization, industrialization, deforestation, poisepopulation, and use of fossil fuels. Normal disasters such as spherequakes, volcanoes, cyclones, placeslide and floods can too privatively desire the environment.

V. Intercommunity among environment and population bud

Humans are an courteous part-among-among of the eco-method of regularity and there is end conformity among ethnical men-folks and environment. Ever gone morals existed ethnicals possess been depending on their environment for prop, cover, and other necessities. There is an inverse intercommunity massive among population bud and environment as poisepopulation allure bring to impertinent commodities on the environment. As ethnical population extension, there is too extension in the claim for prop and other disembodiment founts. It is redundant that the population is deeptained at a roll so that the normal instrument are tit to coalesce the requirement for operation of all stay men-folks.

VI. Neo-Malthusian or pessimistic purposes on population bud

Malthusian theories or pessimistic theories on population bud was extraneous from the purposes of Reverend Thomas Robert Malthus, a British savant who wrote course of essays on the principles of population. There were six editions of his An Essay on the Principle of Population (published from 1798 to 1826) in which he said that if the ethnical population bud is left unchecked the prop furnish allure not be tit to coalesce the wants of ethnicals. He designed the purdumbfounder that opportunity ethnical population grew exponentially, the prop instrument grew barely arithmetically. He too admired that population allure be restrainled normally by indisposition, famine and portraiture. This was named as the pessimistic copy of population bud. Malthus admired in using counteractive checks such as frugality, delayed nuptials and restricting nuptialss in prescribe to restrain population bud. Some persons testd Malthuss hypothesis grounded on the deed that there has been an enhanced urban constructation and cheap ethnical fertility poise the departed few decades gone the divulgation of his theories. However, frequent tranquil admire in his hypothesis that if left unchecked, population bud can dumbfounder earnest wholes for refount availability (Cristina, 2010).


These are collections who too admire in the theories of Malthus and advance population restrain programs for the confer-upon and forthcoming boon of ethnical men-folks. The Neo-Malthusians purdumbfounder so-far contend from Malthus in their avowal on the use of contraceptive techniques for the fount restrain estimates. The neo-Malthusians or the pessimistic purdumbfounder had aggravate concerns encircling the commodities that population bud would possess on environmental deprivation. Opportunity they attended the theories put impertinent by Malthus, this collection of persons strongly attended the purdumbfounder of actively restrainling population bud in prescribe to nullify impertinent collision on the environment. This pessimistic collection are uneasy encircling the commodities poisepopulation may possess on refount depletion and environmental deprivation. There has been a public enjoyment in neo-Malthusian ideologies from the 1950s forwards distinctly subjoined the divulgation of course of tomes by some Malthusian stayers such as Fairfield Osborn (Our Plundered Planet), William Vogt (Road to Survival) and Paul Ehrlich (The Population Bomb). Although frequent critics of neo-Malthusianism test the enjoyment of this hypothesis grounded on deed that the unpractised deflection has led to tit prop constructation, Pessimists such as Paul Ehrlich admire that unchecked population allure ultimately bring to earnest wholes in the forthcoming (Ehrlich, 2009). Neo-Malthusian or the pessimistic purdumbfounder is aggravate encircling the indisputtelling checks but Malthusian said that there is poise among twain indisputtelling and privative checks.

Technological or Optimistic purposes on population bud.

The optimistic copy of population bud was designed by Julian Simon who in his tome The Ultimate Refount (1981) argued that as instrument beend few the cost goes up which in incline engenders incentives for persons to discpoise new fount or furnish alternatives for the expedients. Simon too claims in his tome that the normal instrument are infinite grounded on the advocacy that innovative methods can be used to compel normal instrument suited. Increasing population bud and cheap instrument compel persons to engender innovations and falsehoods to development aggravate prop and all basic wants. The optimistic purdumbfounder said that understanding and technology can poiseend want wholes. Esther Boserup (1910-1999)-Danish economist said requirement is the dowager of falsehood. So, ethnicality allure regularly furnish a way to poiseend their wholes. The optimistic purdumbfounder too said that aggravate persons moderations aggravate alternatives to furnish new materials and discpoise ways to do things.


It can be seen from the over paragraphs that population bud can collision on the specify of environment of our planet. Of the two theories on population bud, I stay the neo-malthusian hypothesis of pessimistic purposes grounded on the subjoined advocacys.

Deforestation for farming

If the ethnical population bud is left unchecked, a day consequenceiveness end when the spheres instrument allure not be consequenceual to stay the requirements of ethnical men-folks. As poisepopulation allure claim increasing prop, disembodiment, and other instrument, ethnicals allure occupy in activities that allure straightly desire our environment and ecosystem. For prompting, encircling 160,000 clear kilometers per of typical rainforests are cleared for urban use thus developmenting in waste of habitat for the biodiversity (Laurance, 1999). Such waste of forests allure co-opeblame to global warming and other privative commoditiess on environment.


In prescribe to coalesce the growing claim of increasing population, ethnicals possess been using technologies such as industrialization for enhanced constructation of prop and other wants. Increased industrialization and urbanization developments in air stain, din stain, and infiltblame stain which are all injurious to our environment.

Increased urbanization allure too moderation diffusion of forests for erection of roads, buildings etc. which raise adds to stain.

Depletion of non-reneweffectual normal instrument and emission of unpractised family gases

Uninferior bud of population allure bring to flying depletion of non-reneweffectual normal instrument such as fossil fuels which are used as fount of disembodiment. The burning of fossil fuel i.e. carbon grounded fuels, enlightenedly forest, coal, oil and normal gas developments telling total of CO2 which is one of the deep unpractised family gases that co-operates to global warming (International Disembodiment Outlook, 2000). The unpractised family commodities deeptains the sphere at comforteffectual weather class but if there is inordinate disengage of CO2 and other injurious gases from the industries and deedories, the unpractised family gases gets amply out of restrain and allure bring to so frequent wholes love continental course, clime exchange, normal disasters and variations of suns out put.

Loss of biodiversity and habitat

Due to growing population, distinctly in the sylvan areas of developing countries, persons practising mutation husbandry underobtain?} slash-and-burn techniques which developments in the stifling of indigenous flora and fauna. It has been reported that closely 140,000 estimation are obsolete entire year due to deforestation activities (Pimm, Russell, Gittleman and Brooks, 1995). Therefore, if population bud is not restrainled, increasing ethnical activities allure raise development in perdition of the habitat and waste of biodiversity. In Bhutan, ethnical-wildmorals distinctly ethnical-elephant contest is increasing and this is enlightenedly due to the waste of habitat for the elephants due to increasing ethnical population and activities (Kuensel, 19 May 2012).

IX. Solutions

There is a want to furnish solutions to reduce the wholes associated delay poisepopulation and environmental deprivation. The governments encircling the universe should possess policies to reduce the population bud scold by increasing use of fount restrain estimates. The governments should too fabricate good-natured-natured-natured policies to shield forests and environment and nullify waste of normal habitat. Innovative purposes and discovery should be executed to extension prop constructation delayout exciting the environment. The governments should extension funding for order and awareness of distinctly the penniless persons for them to shield and obtain?} regard of their environment.

X. Conclusions

In blank poisepopulation can bring to wholes in the construct of depleting normal instrument, environmental stain and deprivation, and waste of habitat. Therefore, imperative steps want to be smitten to husband ethnical population bud to a roll that can be husbandd courteous. The theories founded by Reverend Malthus can be tranquil followed consequently the normal instrument suited now may not be tit in the forthcoming if we do not restrain ethnical population bud.
