Today, barely years later, we are more than 7. Taking into account the fact that human beings appeared on Earth more than four million years ago, what happened in our recent history for the number of inhabitants on the planet to start multiplying exponentially?
The tipping point was generally accepted to be the Industrial Revolution, but there are many smaller revolutions that contributed to population take-off which have brought the planet to its current dangerous overpopulation : revolutions that are medical, technological, agricultural, financial, transport and demographical in nature, among others. China alone is home to 1. Overpopulated areas face many challenges, most of which stem from the impact of climate change or human overexploitation of natural resources, but a recent study published by Nature Communications points to rising sea levels as one of the greatest dangers.
According to this study, coastal areas currently inhabited by million people are set to experience annual flooding by , unless measures are taken to hold back the water — a figure three times higher than previous estimates. Asia is the area at greatest risk of flooding due to climate change , due to its very low-lying land and overpopulation. Of the million people at risk, million live in six countries: Bangladesh, India, China, Vietnam, Thailand and Indonesia.
The Indonesian capital of Jakarta, along with its suburbs, is currently home to over 30 million people and it is expected to be entirely submerged by ; the Indonesian government is therefore considering moving their capital elsewhere. The main reason for this is the continuous extraction of groundwater, which is speeding up the rate at which the city is sinking.
It took hundreds of years to reach one billion inhabitants, yet in little over two centuries this figure multiplied sevenfold. There are a series of factors that favored the spectacular growth:. What does this constant growth mean?
There are several direct consequences of overpopulation:. Other major sources of eutrophication are industry and sewage disposal--both related to population growth. The cost of mediating eutrophication in the U. Cotton or linen production, for example, can involve direct agricultural impacts.
While there is plenty of water on the planet, it is very much a scarce resource. Only 2. One of the byproducts of population growth has been stress on freshwater supplies. According to one report, around 40 percent of the world's population endure water scarcity, and that amount has been projected to skyrocket by as global demand for water increases by 50 percent.
Also consider that population growth is most rapid in part of the world where water is in high demand already, such as Africa and Asia. Human population growth and climate change have grown hand in hand as the use of fossil fuels has exploded to support industrialized societies.
Most fossil fuel consumption comes from developed countries. Deforestation is another important component of greenhouse gas emissions. Globally, forests store more than twice the amount of carbon dioxide than is found in the atmosphere.
There are issues aplenty to overcome. Clearly, initiatives to switch to clean energy sources such as solar, improve agricultural practices, better manage water resources and fully embrace the principles of the circular economy will help us mitigate the impact of population growth. At the other end of the spectrum, policies that encourage family planning, education, gender equity and other measures to help slow population growth will help reduce pressure on the planet.

Today, it is a staggering seven billion plus. This has caused unease that overpopulation will be a problem for our future generations. Overpopulation is a problem that every nation is facing but sometimes over looked by due to lack of understanding and awareness. This is a serious issue that should be taken care of immediately. Overpopulation is an undesirable situation where the number of existing human populace surpasses the carrying capability of Earth.
There are main factors that are contributing overpopulation such as the rising birth rate and declining of mortality rate. Overpopulation occurs when the birth. The ongoing debate on world overpopulation allows many different people to offer their unique opinions, such as Erle C.
These writers offer perspectives that support and conflict the different aspects of the overpopulation issue. Both Ellis and Kotkin believe that overpopulation is not an issue, while Walker and Tal strongly believe that it is. Overpopulation Programs There are many organizations that deal with the problem of overpopulation or problems related to the effects of overpopulation such as environmental effects. All of these groups deal with the issue of overpopulation and the effects that overpopulation.
To begin with, in demography, the term overpopulation refers to a condition wherein the total population of a particular region far exceeds the carrying capacity of the region. Although the term by and large refers to the ratio between population and the available area, the ratio between the population and available resources cannot be ignored. First, the rate at which the population is growing; the data compiled by the United Nations shows that the world population grew by 30 percent between.
Overpopulation The convoluted problems concerning overpopulation remain to be a highly discussed issue in various countries throughout the world. Some issues that are in support of overpopulation include the opportunity to place innovative ideas into action, aids in stimulating the economy, creates job openings in new growing industries, increased human resources, encourages competition, advancement in urbanization and development, creates a demand for industries like farming, and allows for cheaper.
Today the Earth is home to just over 7 billion people and is continuously growing at a rapid rate. It has become clear however as the population has increased, the World is faced. Overpopulation is not an issue many people in developing countries face at this point in time. It should not be taken lightly because it cannot be reversed in a short time period. Changes must be made gradually so that future generations do not suffer consequences that current generations have place upon.
In the present era, there are many issues that pose a threat to our way of life. Overpopulation is one of the most serious threats to mankind. Overpopulation is a serious problem that will eventually have an extremely negative effect on our countries and our planet. Overpopulation is generally defined as an inability of the environment to support the existing population of human or other living things. Overpopulation is an undesirable condition where the number of existing human population exceeds.
The main causes for overpopulation in India and other similar developing countries differ slightly from that of the world. Overpopulation in India is caused by factors like poverty, ignorance, lack of family planning, child labour, and reduced mortality rate, interstate immigration etc. Poverty in India is considered to be one of the prime causes of overpopulation.
Poverty leads to illiteracy and lack of awareness on issues like — contraceptive use and family planning; this, leading to a uncontrolled population growth in deprived areas. The cause of overpopulation in the world is many and they differ from place to place.
At one place migration might causing it, at another place it might have been caused due to poverty. Whatever the cause may be, we must take necessary steps to reduce overpopulation. There are many effects of overpopulation in the world. Overpopulation in a place causes scarcity of available resources leading to deprivation and poverty. Moreover, it also causes unemployment, as the number of persons in need of a particular job, large outgrows the total number of actual vacancies.
Two of the most common effects of overpopulation- social and health are discussed below. There are a variety of social effects of overpopulation, ranging from, poverty, unemployment, poor hygienic conditions and a scarcity of resources for a community. When the population of a particular area rises beyond the destined capacity of that place, then a number of changes in the society are witnessed.
For example, if a fresh water resource is used by more people than it can sustain; then such situation often results in conflicts. People tend to fight with each other over the use of resources. Overpopulation also leads to scarcity of food and unemployment, causing large scale poverty, hunger and poor hygiene. Overpopulation also has an adverse effect on health of an individual, due to scarcity of food and other resources.
The food and other resources, those had been available in abundance, become scarce, when the population of a place grows beyond a specific limit. Moreover, overpopulation is directly related to unemployment and latter could be directly associated to malnutrition and depleting health conditions.
Many people living in a crowded area also results in habitat destruction, reducing the quality of air and other vital parameters, resulting in poor health condition. As more people start living in an area, it becomes imperative to cut down trees and clear vegetation to make houses for them.
Thus, begins the vicious cycle of materialistic growth compromising the health and fitness of humans. People residing in populated areas are often seen living in poor health and hygienic conditions with no access to basic health amenities, clean air and clean water. Overpopulation in area causes evident social and health effects on the individuals and the society as a whole.
From poor health and hygiene conditions to natural resource depletion, unemployment and increase in criminal activities — overpopulation has a hand in all these adversities. It therefore becomes important that we take necessary remedial measures before the populations goes beyond the specified limit. The problem of overpopulation is grave, but as every problem has a solution, so overpopulation too has solutions; though, it may take some time before the results are evident, but the effort would be worth it.
Solutions to eliminate overpopulation in the world are discussed below. For the convenience of understanding, in this heading we will discuss the matter of overpopulation only in developed countries. The main reason behind the concentration of population over a particular area in developed countries is the availability of resources and better growth opportunities. People tend to concentrate over the place where irrigation, water, electricity and other amenities are available in abundance.
Necessary efforts must be made by the respective government to make the basic public amenities to the people in their native place of residence. Any political or military conflict must be resolved quickly by the intervention of world community to prevent cross border migration and population complications at other places. The main causes of overpopulation in India and other countries are poverty, illiteracy and lack of basic knowledge about family planning.
Majority of population in India and other developing nations, still reside in villages, where they lack basic education and other facilities than the cities. People residing in villages still shy from talking on issues like family planning and use of contraceptives is considered a taboo.
Therefore, awareness through education seems to be the only appropriate solution for a developing country like India. People must be told about the significance of family planning and that shying away from it will only aggravate their financial crisis and reduce their social status. It is indeed more economical and practical to feed a family of four than a family of six or ten members. Despite making a number of reforms in these two sectors, the government is also making efforts to make people aware of family planning.
They also teach people about the use of contraceptives to eliminate the possibility of conception. The government is also distributing free contraceptives to remote locations through the PHCs. The most important solutions to overpopulation are education and awareness of people. The more educated and aware the people are, the more remote will be the possibility of overpopulation. The government has made considerable effort towards keeping the population under control but a lot more still needed to be done.
Overpopulation in the world is a global phenomenon and is more evident in developing and underdeveloped countries. Even the developed countries witness a large influx of migratory population from the developing and under developed countries. In the following essay we will discuss on the causes of overpopulation, the problems of overpopulation, state of overpopulation in India and other developing countries and the solution of overpopulation. Illiteracy is one of the main causes of overpopulation in any country over the world.
The countries lacking on the front of education have more population growth than others. Lack of public awareness about family planning issues is one of the prime reasons for overpopulation. People are not aware of the effects of overpopulation and its effects on the society and nation. The act is in disregard to their own financial constraints.
Poor condition of basic health amenities is also a prime cause of overpopulation. Absence of a medical professional and non availability of contraceptives, leads to incessant growth in population. Overpopulation causes the depletion of resources over a particular area. As the number of people using a specific resource increases, its fast consumption results in rapid depletion.
Vital resource like food and water become scarce in case of overpopulation. Even the basic health and transport facilities become rare. Unemployment is one of the most severe consequences of overpopulation.
