According to my research Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life.
Overpopulation will place great demands on resources and land, leading to widespread environmental issues in addition to impacting global economies and standards of living.
The issue is compounded by the difficulty in providing solutions for this problem and misunderstanding of the causes and effects of overpopulation.
Over the last half century the population of the world has exploded. At the time of writing there are seven billion people on the planet and this number is projected to grow in a short period of time. Of all of the environmental challenges facing the planet today overpopulation is one that sometimes slips under the radar. Issues like pollution, climate change and water shortages all seem to take precedence, but overpopulation is one of the main contributors to many other environmental issues.
According to scientist the Earth has a maximum capacity of 9 to 10 billion of people and as I surf through the internet it says that the Earth has now 7.7 billion of people all around the world.
Human overpopulation is among the most pressing environmental issues, silently aggravating the forces behind global warming, environmental pollution, habitat loss, the sixth mass extinction, intensive farming practices and the consumption of finite natural resources, such as fresh water, arable land and fossil fuels, at speeds faster than their rate of regeneration.
Causes of Overpopulation
Due to “Renewable Resources” Poverty is believed to be the leading cause of overpopulation. A lack of educational resources, coupled with high death rates leading to higher birth rates, result in impoverished areas seeing large booms in population.
Poor Contraceptive Use
Though the availability of contraceptives is widespread in developed countries, poor planning on both partners’ parts can lead to unexpected pregnancies. Statistics have shown that in Great Britain 76% of women aged between 16 and 49 used at least one form of contraceptive, leaving a quarter open to unexpected pregnancies.
Decline in the Death Rate
Due to www.conserve-energy-future.com At the root of overpopulation is the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize.
Lack of Family Planning
Most developing nations have large number of people who are illiterate, live below the poverty line and have little or no knowledge about family planning. Getting their children married at an early age increase the chances of producing more kids.
Many people prefer to move to developed countries like US, UK, Canada and Australia where best facilities are available in terms of medical, education, security and employment. The end result is that those people settle over there and those places become overcrowded. Difference between the number of people who are leaving the country and the number of people who enter narrows down which leads to more demand for food, clothes, energy and homes.Technological Advancement in Fertility Treatment
With latest technological advancement and more discoveries in medical science, it has become possible for couple who are unable to conceive to undergo fertility treatment methods and have their own babies. Today there are effective medicines which can increases the chance of conception and lead to rise in birth rate. Moreover, due to modern techniques pregnancies today are far more safer.
Better Medical Facilities
Following this came the industrial revolution. Technological advancement was perhaps the biggest reason why the balance has been permanently disturbed. Science was able to produce better means of producing food, which allowed families to feed more mouths. Medical science made many discoveries thanks to which they were able to defeat a whole range of diseases. Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines. Combining the increase in food supply with fewer means of mortality tipped the balance and became the starting point of overpopulation.
Effects of Overpopulation
Conflicts and Wars
Overpopulation in developing countries puts a major strain on the resources it should be utilizing for development. Conflicts over water are becoming a source of tension between countries, which could result in wars. It causes more diseases to spread and makes them harder to control. Starvation is a huge issue facing the world and the mortality rate for children is being fuelled by it. Poverty is the biggest hallmark we see when talking about overpopulation. All of this will only become worse if solutions are not sought out for the factors affecting our population. We can no longer prevent it, but there are ways to control it.
Rise in Unemployment
When a country becomes overpopulated, it gives rise to unemployment as there fewer jobs to support large number of people. Rise in unemployment gives rise to crime as people will steal various items to feed their family and provide them basic amenities of life.
High Cost of Living
As difference between demand and supply continues to expand due to overpopulation, it raises the prices of various commodities including food, shelter and healthcare. This means that people have to pay more to survive and feed their families.
Depletion of Natural Resources
The effects of overpopulation are quite severe. The first of these is the depletion of resources. The Earth can only produce a limited amount of water and food, which is falling short of the current needs. Most of the environmental damage being seen in the last fifty odd years is because of the growing number of people on the planet.
