Population growth refers to the change or the increase in size of a population overtime, this can either be positive or negative depending on the balance of births and deaths of a particular area. This assignment will therefore centre on how the increase in global population had affected the climate, how it led to high unemployment rate and poverty and the damage of environment.

Research questions

  • What is the effect of climate change and food shortages on the world’s population?
  • When does population growth lead to unemployment and poverty?
  • In what way may population growth damage the environment?

Growing Population, Climate Change and Food Shortages

The population of the world, now somewhat in excess of three billion persons, is growing at about two per cent a year, or faster than at any other period in man’s history. While there has been a steady increase of population growth during the past two or three centuries, it has been especially rapid during the past 20 years.

Climate change is caused by greenhouse gas emissions trapping heat and altering weather patterns. Population and climate change can be linked through adaptation reducing vulnerability to the adverse effects of climate change and, more controversially, through mitigation reducing the greenhouse gases that cause climate change. The contribution of low-income, high-fertility countries to global carbon emissions has been negligible to date, but is increasing with the economic development that they need to reduce poverty.

Rapid population growth endangers human development, provision of basic services and poverty eradication and weakens the capacity of poor communities to adapt to climate change. Significant mass migration is likely to occur in response to climate change and should be regarded as a legitimate response to the effects of climate change. It has been said that every person on earth causes carbon emissions through consumption of products and energy .

And also causing environmental change by delivering more producers, populace development intensifies each other issue related with changing climate designs. For instance, environmental change influences biodiversity levels by taking species outside of their natural cut-off points. In the meantime, expanding interest for space and assets implies human populace puts always species in danger by crushing characteristic territories. Plants and creatures are then limited to littler and non-contiguous territories, bringing about inescapable eradication.

As barometrical carbon dioxide rises, a more prominent extent is broken up into the seas. Through buffering from existing maritime carbon, this disintegration causes sea fermentation. This influences angle, corals furthermore, different species. Again populace development multiply affects these species as more individuals put more request on marine assets for sustenance and vocations. This can prompt botch and issues, for example,the crumple of North Sea cod stocks .

The four possible cases where climate change affect food securtity are temperature increase, changing patterns, rising sea levels and water. At the point when temperatures rise, they prompt warmth worry for plants, expanding sterility and bringing down in general profitability. Higher temperatures additionally increment vanishing from plants and soils, expanding water necessities while bringing down water accessibility.

Evolving designs, in many spots, developing seasons are changing, biological specialties are moving, and precipitation is winding up more unusual and problematic both in its planning and its volume. This is prompting more noteworthy vulnerability and increased dangers for ranchers, and conceivably disintegrating the estimation of customary farming learning, for example, when to plant specific yields. Rising ocean levels pollute waterfront freshwater aquifers with salt water. A few little island states are as of now having difficult issues with water quality, which is influencing agrarian efficiency.

Higher oceans additionally make networks more helpless against storm floods which can be 5-6 meters high. The connections between environmental change, water shortage and decreases in rural efficiency could prompt provincial strains and even open clash between states effectively battling with deficient water supplies because of rising populaces and over-pumping of groundwater.

Magadoff and Tokar (2009) concluded that 12% of the global population –approximately 36 million people- suffer from hunger and live without secure access of food. Decreased food production in less developed countries, increases in the price of food, and growing production of bio-fuels are responsible for current rates of food scarcity. Global warming, crop diversity loss and urban sprawl also affect agriculture production. Kendall and Pimentel (1994) note that current per capita grain production seems to be decreasing worldwide. The situation is particularly distressing in Africa, where grain production is down 12% since 1980. Africa only produces 80% of what it consumes (Kendall and Pimentel, 1994:1999) .

Growing Population, Unemployment and Poverty

Overpopulation causes more competition for employment. Not exclusively does expanded rivalry for work make it harder to discover a vocation, bosses can enlist representatives for a lower wage for fact that there are a greater number of candidates than employments to go around. Lower compensation amid a period when the interest for items is higher than can be delivered brings down your buying force and upgrades the fantasy that there are less employments. during tough times, workers are likewise less inclined to surrender an occupation they look for the chances are against them to locate a better employment.

Through the nineteenth and the primary portion of the twentieth century, interllectuals were generally isolated between the devotees of Malthus and the adherents of Marx. Roughly expressed, Malthusians trusted that high rates of populace development sentenced social orders to pretty much lasting conditions of underdevelopment and that just by breaking the iron linkage of high richness to destitution could genuine enhancements in ways of life be accomplished. Marx, then again, contended that high fruitfulness was a manifestation, not a reason, of destitution and said that just by acquiring regards to an extreme change in the hidden reasons for neediness would expectations for everyday comforts rise and birth rates start to fall.

Population trends and elements can enormously affect prospects for neediness decrease and economical advancement. Neediness is impacted by – and impacts – populace elements, including populace development, age structure, and rustic urban appropriation. The majority of this critically affects a nation’s improvement prospects and prospects for raising expectations for everyday comforts for poor people. Interests in better wellbeing, including regenerative wellbeing, are basic for singular security and for decreasing mortality and grimness, which thusly enhance a nation’s profitability and improvement prospects.

Throughout the decades a momentous changes in general wellbeing have happened, for example, progressions in discovering inoculations for perilous sicknesses. Different factors, for example, better sustenance and sanitation have brought down the passing rates. These headways in wellbeing have brought better expectations for everyday comforts as well as have enormously added to the populace increment, particularly a Populace patterns and elements can enormously affect prospects for neediness decrease and economical advancement.

Neediness is impacted by – and impacts – populace elements, including populace development, age structure, and rustic urban appropriation. The majority of this critically affects a nation’s improvement prospects and prospects for raising expectations for everyday comforts for poor people. Interests in better wellbeing, including regenerative wellbeing, are basic for singular security and for decreasing mortality and grimness, which thusly enhance a nation’s profitability and improvement prospects saw in the wake of the twentieth century. The population increment seen from the twentieth to the 21st centuries has influenced the business circumstance. This is especially valid in the creating and minimum developed countries where populations burgeon faster than the rate of economic development.

Although birth rates are generally declining, immigration contributes significantly to the population growth of a country. Migration from developing to developed countries is a cause for concern for the latter. The high influx of immigrants to countries such as the United States strains social systems such as healthcare. This is largely due to illegal immigrants not contributing to the taxation system. Immigration, especially that which is illegal, has also resulted to lower wages and competition for jobs between immigrants and locals. Illegal immigrants also remain unemployed for longer periods of time, therefore exacerbating the unemployment situation.

Access to sexual and conceptive wellbeing, including family planning, can influence populace elements through deliberate fruitfulness decrease and decreases in newborn child and maternal mortality. Enhanced regenerative wellbeing likewise helps people, especially young ladies, break out of intergenerational cycles of destitution. Whenever ladies and couples are engaged to arrange for whether and when to have youngsters, ladies are better empowered to finish their instruction; ladies’ independence inside their family units is expanded; and their acquiring power is made strides. This fortifies their monetary security and prosperity and that of their families. Aggregately, this adds to advancement and destitution decrease.

Growing Population, and Environmental Damage

Environmental change on earth is as old as the planet itself, around 4 billion a long time. Homo sapiens has adjusted natural conditions all through his vocation of Earth subject for 4 million years. In any case, there is in no way like the twentieth century. For the first time we have changed environments with such power, on such scale, speed andmeasurement as at no other time. Population growth has had a negative impact on the quality of the environment.

As more land is used for agriculture or living purposes, the environment changes drastically. As the population of humans grows in certain cities or rural areas, more resources must be used to maintain the well-being of the population. With the increasing pressure on available resources, many habitats are being destroyed. Humans are using up more resources and the amount and nature can’t replenish those resources fast enough to supply our needs. The atmosphere is also negatively impacted by population growth.

As the population increases, there is an increase in the amount of pressure put on the agricultural sector. Farming is a major human activity that has transformed the land masses and it has become a direct route in which humans have affected the environment. In many countries, the need for food is so great that natural habitats are destroyed and transform into agricultural lands.

The atmosphere is a thin gaseous envelope that surrounds the earth. It is about 100 km thick and a very dynamic place. Besides oxygen and nitrogen the atmospheric layer contains mostly the trace gases carbon dioxide, ozone and sulfur dioxide. 5 Additionally, methane, chlorofluorocarbons (CFCs) are present. In the twentieth century, human action put more than gases into the atmosphere. Fossil fuel burning, metal smelting, and waste incineration released thousands of tons of potentially toxic metals into the air as dust. Human health suffered also from lead emissions, which came mainly from car exhausts.

For a large portion of the human history (up to 1900), individuals couldn’t contaminate the air but by kicking up a little residue. At that point a large portion of a million years back we saddled fire. We burnt scenes, discharging carbon dioxide and different gases into the air. In any case, it was not much. Regular procedures, including the enduring work of quadrillions of organisms and the infrequent major volcanic ejection, administered the air.

At the point when mankind possessed buckles and started to consume fuel wood for warming and cooking, indoor contamination made its presentation. Darkened lungs and eye diseases are regular among embalmed bodies from Paleolith. Open air contamination of any genuine outcomes came just with urban communities. Early urban areas, similar to some cutting edge ones, frequently oozed sharp scents by virtue of rotting substance, nourishment, and defecation.

Urban areas under attack, with no chance to trade the wellsprings of smells, could end up insufferable like Hermopolis in old Egypt, which surrendered to Nubian besiegers when its air drove the occupants to incline toward Nubian kindness to their own particular stench. Urban smoke obscured marble in antiquated urban communities, irritated established journalists like Horace, and incited a spate of laws among the old Jews. Antiquated metallurgy included new toxins; the same did mining and purifying in old Mediterranean world. The principle metallic contaminations were copper and lead. There are numerous chronicled precedents on this direct beginning from China toward London.

The histories of urban air in the twentieth century were variations on earlier themes. Regional and global air pollution, on the other hand, had scarcely existed in prior centuries. Domestic hearths never, and cars, rarely, caused noteworthy regional air pollution. That required large-scale combustion of heavy industry generating pollutants that would hang around in the air for days or weeks.

The main pollutants responsible for regional-scale air pollution – sulfur dioxide, particulates, and nitrogen oxides – have residence times that allow them to stay aloft and spread with the wind. Regional air pollution grew acute where heavy industry enjoyed high prestige and political support, where the objections of the landed interests counted for little, where dirty coal was the cheapest fuel, and where large-scale smelting took place. The second Industrial Revolution (1870 – 1914) required plenty of copper mining and smelting in Spain, Chile, Japan, North America, and eventually southern Africa.

Concluding Remarks

The ever-growing global population can be prevented. When people start realising the damages it cause, they will look for alternatives such as family planning because the more the people, the more unemployment and environmental damage there is.
