population growth, low fertility, sustained productivity increases, and rising consumption for the majority. The reason for this increase is mainly due to a lack of knowledge of family planning. While in developing countries, people are not well educated and have no proper idea about family planning. Mostly people come from rural areas to urban areas/cities for job opportunities or employment and improvement in lifestyle. It is one of the key measures of a nation’s population growth. Even many of the renewable resources like forests, grasslands etc. Under certain condi-tions moderate population growth can be benefi-cial. Viewing the issue of increasing population optimistically, one may say that overpopulation means the increase in human resources. 1. Greater number of people requires a greater number of resources. Conclusion: To live a better life every family needs to have proper family planning in a manner to provide their kids with complete nutritious food, proper shelter, the best education, and other important resources. In the last 100 years improved medical facilities and technological advancement has increased the life expectancy to 60.3 years and 60.5 years, respectively for the Indian males and females. Some examples of naturally regulated population growth are rodents, rabbits, and various insect populations (e.g., army worms and locusts). Thus controlled population is the key to the success for every Country in the World. It is expected to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. Plagiarism Prevention 4. In China, the ratio of boys to girls became 140 : 100 in many regions which led to scarcity of brides. Read this article to learn about the causes, characteristics and explosion of population growth! Government should also provide some incentives or tax exemption to curb overpopulation. Growth must be checked to avoid this catastrophe. Understanding the factors which affect population growth patterns can help us plan for the future. Although many environmental trends are grim, there exist clear paths forward toward a more sustainable world: one where people steward resources for the future and share habitat and resources generously with other species. Illiteracy is another important cause of overpopulation. Each day 40,000 children die from malnutrition and its related diseases. The rural population on the other hand is … agriculture showed a growth rate of 3.2% per annum, whic h ex ceeds the population growth rate of 2.0% annually over the period, while annual growth rate of per capita income was 3.1% between 1980 and (b) Transitional phase that occurs with the advent of industrialization providing better hygiene and medical facilities and adequate food, thereby reducing deaths. Discoveries and inventions in food and health sectors have saved lives. And the population of the world is rising steadily year on year. Equity and social justice to all, allowing everyone to enjoy a good standard of living is the need of the hour that can voluntarily help in achieving a stabilized global population. It is an important parameter affecting future growth of a population. As a result, the ecological life-support systems are getting jeopardized. There has been a dramatic reduction in the doubling time of the global human population, as we have already discussed. Causes, Effects, and Solutions: Overpopulation means an increase in the number of people in an area than the number, the resources of that particular area can sustain. Forests are depleting to cater to the growth of urbanization that is affecting animals in the forest, causing pollution and imbalance in ecology. The earth does not contain enough resources to indefinitely sustain the current enormous population growth. •Population growth is a problem of human welfare and of development. Mostly people who are contributing for population growth are illiterate and living below of poverty line. are under tremendous pressure. Moreover, due to awareness, people go to the hospital for routine checkups and delivery, which are safer for the mother and baby. This shortage of productive cropland is, in part, the cause of the food shortages and poverty that many humans are experiencing today (Leach, 1995). Owing to modern medications and improved treatments to various illnesses, the overall death rate has gone down. it is called linear growth. They are unable to understand the harmful effects that overpopulation has. Causes of Population Growth. The world cropland average is only 0.27 ha available per capita, or roughly one-half the needed amount (Table 1). Hot Climate. •Rapid population growth can … As the number of annual deaths fell, while births remained constant, so the population increased. In many areas, there is simply not enough food to feed the growing populations. As we know, some of the resources available to us come in limited quantities, for example, fossil fuels. Changing climate patterns, rise in sea level are a few of the consequences that we might have to face due to environmental pollution. High Illiteracy 4.

When the population explosion happened, these resources are becoming rarer and will one day run out completely. The ever-increasing population will eventually leave no nation capable of providing its people with the resources they need to thrive. The average life expectancy, over the globe, has risen from 40 to 65.5 years over the past century. On 11th May, 2000 we became 1 billion and now we can say that every 6th person in this world is an Indian. Although this rate has declined in the last 50 years, but the pattern differs widely in developed and developing countries. The exponential influx in human Crowding of immigrants in certain parts of the world, results in an imbalance in the density of population. Due to ignorance, they do not take to family planning measures, thus contributing to a rise in population. However, the matter of concern is that more than 90% of the global population is concentrated in developing nations which have a growth rate a little more than 2%, and a doubling time of less than 35 years. Demographic transition is already observed in most developing nations. There are circumstances which can create sentiment in the population that will inspire population growth. That is because a growth rate exceeding 0% has ex-ponential implications. The value of TFR varies from 1.9 in developed nations to 4.7 in developing nations.

Population growth is the increase in the number of individuals in a population.Global human population growth amounts to around 83 million annually, or 1.1% per year. Introduction: Population Growth is becoming a huge issue in our country and the world today. The purpose of this unit is to examine some important factors about overpopula-tion. In India, life expectancy of males and females was only 22.6 years and 23.3 years, respectively in 1900. Those lacking education fail to understand the need to prevent excessive growth of population. There are two very important views on population growth which need a mention here: According to Malthus, human populations tend to grow at an exponential or compound rate whereas food production increases very slowly or remains stable. Rise in the amount of release of greenhouse gases causing global warming, which causes the melting of ice from iceberg and glaciers. When birth plus immigration in a population are just equal to deaths plus emigration, it is said to be zero population growth. It is the average age that a new-born infant is expected to attain in a given country. Population explosion is causing severe resource depletion and environmental degradation. The very large population becomes a problem when there isn’t enough space to live and not enough food and supplies to live off of. Typically, such effects result in the cycling between periods of population growth and periods of population decline until it can reach homeostasis within a particular ecological niche. It creates social, cultural and political awareness in people and makes them advanced. Thanks to the new discoveries in nutritional science, we have been able to bring in increase in the fertility rates of human beings. The size of population keeps on changing. The size and demographics of the population change when: 1. fewer children are born; 2. families with children move to larger towns and cities; 3. young and better-educated people move to larger towns and cities. According to Karl Marx, population growth is a symptom rather than the cause of poverty, resource depletion, pollution and other social ills. In addition to depleting resources, overpopulation increases environmental problems. Medicines of today can boost the reproductive rate in human beings. If the inhabitants of various countries migrate to a particular part of the world and settle over there, the area is bound to suffer from the ill effects of overpopulation. However, Earth can produce a limited amount of water and food, which is lesser in comparison to consumption, leading to an increase in prices. One of the reasons for the fast-rising population in India is its hot climate. Population growth takes place exponentially and that explains the dramatic increase in global population in the past 150 years. 1) Population growth causes a dis- proportionate negative impact on the environment. When a quantity increases by a constant amount per unit time e.g. A country can only get success when its citizens are healthy and live a happy and content life. 150 million children in the world suffer from poor health due to food shortages. Thus, science has led to an increase in birth rate. This has resulted in an increase in the life expectancy of individuals. If the current growth rates continue, it will have 1.63 billion people by 2050 and will become the most populous country surpassing China. This exponential population growth that our planet has experienced over the last 150 years has had some severe negative effects. In simple terms: if a combi-nation of birth and growth figures only appears to cause a modest population growth initially, then this TFR is defined as the average number of children that would be born to a woman in her lifetime if the age specific birth rates remain constant.

In slum, areas government has continuously provided some awareness programs to make understand families about the hard life they will have to face with four or five or more children. Labour Force: The labour force in an economy is the ratio of working population to total population. 2) Problems of population size and growth, resource utilization and deple- tion, and environmental deterioration must be considered jointly and on a global basis. There are also other conditions which seem inversely related. Immigration is a problem in some parts of the world. These are usually immediate, or short lived, occurrences and can cause rapid growth. The invention of vaccines and discovery of antibiotics such as penicillin saved thousands of lives and were a key factor in unfettered population growth. If the rates of emigration from a certain nation do not match the rates of immigration to that country, overpopulation makes its way. Mostly people who are contributing for population growth are illiterate and living below of poverty line. Many environmental, social, and economic problems either stem from or are increased in magnitude by the overpopulation problem. In the 20th century, human population has grown much faster than ever before. … In Japan and Sweden, life expectancy is quite higher, being 82.1-84.2 for females and 77-77.4 for males, respectively. Malthus and the classical economists were writing at a time when in England population growth was accelerating. It increases or decreases according to time and space. ADVERTISEMENTS: Some of the most important causes of population growth in India are as follows: 1.

There is continuous increase in school and campus going students due to the increase in population. It is the percentage of infants died out of those born in a year. The brighter side of it is that we have been able to fight many diseases and prevent deaths. The current rate of population growth is now a significant burden to human well-being. This unprecedented growth of human population at an alarming rate is referred to as population explosion. Overpopulation has increased the acts of violence and aggression as people are competing with each other for getting resources and achieving a good lifestyle. Figure 1. He believed that social exploitation and oppression of the less privileged people leads to poverty, overcrowding, unemployment, environmental degradation that in turn, causes over population. Our resources like land, water, fossil fuels, minerals etc. Therefore, the rapid rates of urban population growth are no longer the most pressing concern but the absolute population size of the huge urban centers, especially those in Asia and Africa. 1, 3, 5,7 etc. The most obvious and common impact is that overpopulation has put a great strain on the natural resources of the earth.
