The Effect of Overpopulation on Environment - Research Paper Example : kinenbicounter.info
While the likelihood of man-made global warming may be an increasingly debatable issue, most would agree that there is definitely something. Overpopulation is associated with serious negative environmental impacts. ranging from the impacts of over-farming, deforestation, and water pollution The relationship between overpopulation and environmental impacts. The effect of human overpopulation on the environment has been and is a Mass The problem with water is not only overconsumption, but also pollution. .. For example, the prey-predator relationship can be considered in the food chain.
Center for Biological Diversity Click for source Depletion of Natural Resources As the human population continues to explode, finite natural resources, such as fossil fuelsfresh water, arable land, coral reefs and frontier forestscontinue to plummet, which is placing competitive stress on the basic life sustaining resources and leading to a diminished quality of life.
Each person on Earth now requires a third more land to supply his or her needs than the planet can supply. Furthermore, intensive farming kills beneficial insects and plantsdegrades and depletes the very soil it depends oncreates polluted runoff and clogged water systemsincreases susceptibility to floodingcauses the genetic erosion of crops and livestock species around the worlddecreases biodiversityand destroys natural habitats.
Elevated Crime Rate As human overpopulation drives resources and basic necessities, such as food and water, to become scarcerthere will be increased competitiveness for these resources which leads to elevated crime rates due to drug cartels and theft by people in order to survive. As Aisha Tariq of the Pakistan Times states"It has been observed that the countries which have balanced population, crime rate is very low in such regions.
When people are not provided with the basic necessities, it elevates crime rate. These situations are especially dire for populations in Uganda, Nigeria, and Bangladesh, which will double and, in some cases, even triple over the next 40 years.
A child suffering extreme malnutrition in India, According to the World Health Organization"Every three seconds a young child dies - in most cases from an infectious disease. In some countries, one in five children die before their fifth birthday. Every day 3 people die from malaria - three out of four of them children. Great Apes - the Road Ahead. The range of estimates is enormous, fluctuating from million people to more than one trillion.Breaking the dependence between overpopulation and polution
Scientists disagree not only on the final number, but more importantly about the best and most accurate way of determining that number—hence the huge variability. The majority of studies estimate that the Earth's capacity is at or beneath 8 billion people. PDF How can this be? Whether we have million people or one trillion, we still have only one planet, which has a finite level of resources.
The answer comes back to resource consumption. People around the world consume resources differently and unevenly. An average middle-class American consumes 3.
So if everyone on Earth lived like a middle class American, then the planet might have a carrying capacity of around 2 billion. However, if people only consumed what they actually needed, then the Earth could potentially support a much higher figure. But we need to consider not just quantity but also quality—Earth might be able to theoretically support over one trillion people, but what would their quality of life be like?
Would they be scraping by on the bare minimum of allocated resources, or would they have the opportunity to lead an enjoyable and full life? More importantly, could these trillion people cooperate on the scale required, or might some groups seek to use a disproportionate fraction of resources?
If so, might other groups challenge that inequality, including through the use of violence? These are questions that are yet to be answered. Population distribution The ways in which populations are spread across Earth has an effect on the environment. Developing countries tend to have higher birth rates due to poverty and lower access to family planning and education, while developed countries have lower birth rates.
These faster-growing populations can add pressure to local environments. Globally, in almost every country, humans are also becoming more urbanised. Bythat figure was 54 per cent, with a projected rise to 66 per cent by While many enthusiasts for centralisation and urbanisation argue this allows for resources to be used more efficiently, in developing countries this mass movement of people heading towards the cities in search of employment and opportunity often outstrips the pace of development, leading to slums, poor if any environmental regulation, and higher levels of centralised pollution.
Population and environment: a global challenge - Curious
Even in developed nations, more people are moving to the cities than ever before. The pressure placed on growing cities and their resources such as water, energy and food due to continuing growth includes pollution from additional cars, heaters and other modern luxuries, which can cause a range of localised environmental problems. Humans have always moved around the world. However, government policies, conflict or environmental crises can enhance these migrations, often causing short or long-term environmental damage.
For example, since conditions in the Middle East have seen population transfer also known as unplanned migration result in several million refugees fleeing countries including Syria, Iraq and Afghanistan. The sudden development of often huge refugee camps can affect water supplies, cause land damage such as felling of trees for fuel or pollute environments lack of sewerage systems.
Unplanned migration is not only difficult for refugees. Having so many people living so closely together without adequate infrastructure causes environmental damage too. Population composition The composition of a population can also affect the surrounding environment. At present, the global population has both the largest proportion of young people under 24 and the largest percentage of elderly people in history. As young people are more likely to migrate, this leads to intensified urban environmental concerns, as listed above.
Life expectancy has increased by approximately 20 years since While this is a triumph for mankind, and certainly a good thing for the individual, from the planet's point of view it is just another body that is continuing to consume resources and produce waste for around 40 per cent longer than in the past. Ageing populations are another element to the multi-faceted implications of demographic population change, and pose challenges of their own.
For example between andJapan's proportion of people over 65 grew from 7 per cent to more than 20 per cent of its population.
The Effect of Overpopulation on Environment Paper
This has huge implications on the workforce, as well as government spending on pensions and health care. Increasing lifespans are great for individuals and families. But with more generations living simultaneously, it puts our resources under pressure.
Population income is also an important consideration. The uneven distribution of income results in pressure on the environment from both the lowest and highest income levels. They may also be forced to deplete scarce natural resources, such as forests or animal populations, to feed their families.
On the other end of the spectrum, those with the highest incomes consume disproportionately large levels of resources through the cars they drive, the homes they live in and the lifestyle choices they make.
On a country-wide level, economic development and environmental damage are also linked. When these gases and particles accumulate in the air in high enough concentrations, they can harm us and our environment. More people in cities and surrounding counties means more cars, trucks, industrial and commercial operations, and generally means more pollution.
It may cause air pollution by the fumes and exhaust coming from the tail pipe. It will go to the air and when we breathe it in, we could get sick. For instance, in China, air pollution problems are occurring serious. Last Julyair pollution has lead o cancer and repository disease.
It caused 2 million deaths per year in the worldwide. Land pollution is also a common thing and it happens dues to the increasing population. Population growth results increases the demand for food production. Since the arable land in many Of the overpopulated regions is limited, farmers begin to cultivate dry, hilly, nutrient-poor areas that are not very suitable for farming.
Exploiting such lands makes them easily susceptible to erosion and loss of nutrients. For example, in search for farmland in Indonesia, peasants have been planting their crops on steep slopes. Globally, the statistics are even more frightening. It is estimated that 1. And Mexico combined, have lost much of their agricultural output capability in the last 50 years. Besides, land can become polluted by household garbage and by industrial waste. InAmericans produced about million tons of garbage consisting of product packaging, grass clippings, furniture, clothing bottles, food scraps, newspapers, appliances, paint and batteries.
There are lots of non-biodegradable waste including containers, bottles and cans made of plastic. Dumping of toxic materials such as chemicals and paints makes the areas surrounding the industries look very fifth.
