If we are going to read all the information about population growth on this page, then definitely read the post completely.

On the previous page, we have shared the information about the Constitution of India, so read that article as well.

Let us read and understand all the information about population growth today.

what is population growth

Population growth is a situation where the human population exceeds the actual population of the Earth.

Overpopulation is caused by many factors. Low mortality rate, better medical facilities, lack of precious resources are some of the reasons which result in population growth.

Population Growth Logic

Two facts emerge from population growth.

1. Thomas Malthus first theorized in 1798 that excessive population growth would deplete natural resources and eventually lead to disease, starvation and death.

At the time he made his prediction, the world population was only 800 million, but now, it is over 7 billion.

2. On the other hand, many theories suggest that population growth can have as many positive effects as negative ones.

due to population growth

Population growth can be due to the following reasons.

1. Improving Medical Knowledge

With the advancement in technology, the treatment of all kinds of diseases has become possible today.

This in turn leads to overpopulation as people live longer and thus more people join together to become overpopulated at the same time.

2. Decline in Mortality

Medical improvements coupled with better food supplies have led to a drastic drop in mortality.

When the birth rate remains unchanged and the death rate decreases, it means a positive effect on population growth.

3. Industrial and Agricultural Revolution

Due to the use of machines and the use of fertilizers and pesticides, the production of food and other goods was greatly increased.

So people were able to have more children, which also led to more children. As a result of which a large number of population is increasing at this time.

4. Progress in Food Production

Farmers have improved their knowledge about agricultural techniques. Hence they are able to increase the yield of their crop. This increased wealth resulting in more children and thus more population growth.

5. Poverty

Why should poverty contribute to population growth?

This is because poor people often do not have government pension schemes. Thus, when he is not able to work, he has to depend on his children.

Especially in poor developing countries, the number of children is often much higher than in developed countries.

In addition, children are often required to work on their parents’ farm to be able to cultivate their land which also contributes to the increase in population.

6. Religious Concerns

Another reason for overpopulation is that many people believe it is a sin to have an abortion or even use contraceptives. Thus, without the use of contraceptives, population growth is a natural consequence.

7. Migration and Urbanization

Progress in the process of urbanization has continued over the past decades. This is because the demand for work is increasing from agriculture to the service sector.

In such a situation, people have to move to cities in search of work. This can lead to overpopulation of some areas.

8. Family Planning

In many countries, people get married at a very young age. Thus, they are likely to have more children during their lives.

Furthermore, due to lack of education and family pressures, women see it as their responsibility to have as many children as men want as they are often told that raising children is a woman’s sole purpose. This problem is particularly serious in developing countries.

advantages of population growth

Following are the advantages due to population growth.

1. Economic boost

Many scholars of the modern era have pointed to the economic benefits of population growth.

In the last three decades of the 20th century, the Harvard Initiative for Global Health reported that per capita income increased by two-thirds, with the world’s total population doubling.

Countries which have more population. There are more people working there.

Let’s take a look at China. China has experienced massive population growth and today, the country is one of the largest economies in the world.

2. Growing Techniques

Opponents of population growth have often condemned the burden on resources. However, Danish economist Esther Bosrup has argued that a growing population pressures society to create new technology to better serve the public.

For example, high-yielding crops have been developed to increase food production on a large scale for a growing population.

Also countries that have shown a decline in population growth. For example, Japan is facing a kind of crisis.

Japan has the oldest population in the world and has the largest population of elderly people. This has been a matter of concern for the nation as Japan’s future is in danger due to fewer children.

Disadvantages of Population Growth

Following are the disadvantages of population growth.

1. Environmental plight

Over population has an adverse effect on the environment.

Since we have to produce large quantities of food to provide for as many people as possible, we have to use more land and resources to make ends meet.

More land use is not possible without deforestation. Deforestation leads to a decline in species diversity. In addition, local tribes lose their homes and their entire culture.

In addition, to produce more goods for our daily life, fossil fuels are needed in greater quantities. Burning fossil fuels releases harmful chemicals and causes acid rain.

Additionally, it contributes to global warming. Apart from this, noise pollution is also likely to increase due to high population density.

2. Depletion of Natural Resources

Another problem of overpopulation is the depletion of natural resources. Our planet can only provide a limited amount of food and water.

When our population increases, we will soon reach a point where we will not have enough food and water to feed all the people.

Even today people are dying of hunger everyday. Due to more population, this problem will get worse in future.

3. Conflict

Another consequence of overpopulation is the increasing number of conflicts. Since people have to fight for their share of resources to survive.

As the population progresses, the possibility of conflicts will also increase because limited amount of resources will have to be distributed among the increasing number of people for which people will fight amongst themselves.

4. Increase in death rate

With the increasing number of people, everyone has to struggle hard to get enough food. Those who are not able to do so will be left behind, resulting in increased mortality.

5. Loss in Biodiversity

Population growth can also lead to loss of biodiversity. Since we need more space to farm or live, we destroy the natural environment of many species.

This problem is especially serious in the Amazon rainforest. Many species become extinct every year due to farming and related issues.

6. Increase in pollution

Pollution is likely to increase due to overpopulation. Because on our planet we have to produce more food and other things for daily life.

This production of material goods increases all kinds of pollution. The burning of fossil fuels pollutes the air. Our rivers, lakes and seas also get polluted by dumping and disposal of waste.

Our ground water is getting polluted due to excessive use of fertilizers and pesticides. In addition, light pollution may also increase due to high population density.

7. Ecological collapse

Overpopulation can also cause a kind of ecological collapse. Since humans prefer some types of fish much more than others, this can lead to a serious ecological problem.

Many of our favorite fish consume large amounts of smaller fish. If the numbers of any of these fish are reduced, the balance of our oceans will be disturbed.

8. Excessive Cultivation

To meet the demand for food, farmers have to use increasing amounts of fertilizers and pesticides.

This leads to soil pollution and also adversely affects our ground water due to chemicals permeating through the soil.

In addition, some animals become contaminated by eating crops containing high levels of pesticides.

9. Excessive use of fossil fuels

More population is likely to increase the use of fossil fuels. Fossil fuels are used in many different occasions in our life, for example to drive a car, etc.

The use of fossil fuels is harmful to our environment as the gases generated in industrial processes also contribute to global warming and air pollution.

With the increasing number of people, the possibility of desertification will increase as more land available will be used for farming.

10. Rising Chance of Pandemic

population growth

Overcrowded living conditions and poor sanitation can lead to a serious epidemic of malnutrition.

This will be a big problem for poor people in developing countries as they do not even have money to pay for medical treatment when necessary.

11. Rising Cost of Living and Housing

With limited space to build homes and other infrastructure, costs are likely to increase due to a growing population.

With the increase in population, this problem will become even bigger. An increasing number of people will strive to live in the best places on earth. Since all types of goods and space are limited, the prices of commodities will increase due to increased demand.

solution to the problem of population growth

We can solve the problem of population growth in the following ways.

1. Improving Family Planning

People around the world should be aware of how much hard work and struggle it takes to meet the needs of a family. This will help us greatly in limiting the number of people on our planet.

2. Raising Awareness

People’s awareness about the topic of population growth should be increased. Many people have never heard of this issue as it is quite normal for them to have more and more children.

If he knows about the issue of population growth then we can be of great help in reducing the population growth.

3. Education

Education is also important in reducing the problem of overpopulation. As we saw earlier, poor people are more likely to have children than rich people.

This is because poor people usually do not have pension schemes and thus are dependent on their children.

Thus, education can help people to come out of poverty and thus it can indirectly contribute in reducing population growth.

4. Birth Control

If people do not become responsible for reducing the number of children, then the government will be forced to make strict rules. A prime example of this is China.

Most populated countries in the world

Country Population (2020)
China 1,439,323,776
India 1,380,004,385
United States 331,002,651
Indonesia 273,523,615
Pakistan 220,892,340
Brazil 212,559,417
Nigeria 206,139,589
Bangladesh 164,689,383
Russia 145,934,462
Mexico 128,932,753
Japan 126,476,461
Ethiopia 114,963,588
Philippines 109,581,078
Egypt 102,334,404
Vietnam 97,338,579
DR Congo 89,561,403
Turkey 84,339,067
Iran 83,992,949
Germany 83,783,942
Thailand 69,799,978


Population growth is a serious threat to our entire environmental system. This is likely to lead to serious conflicts and wars as people will fight for resources to meet their daily demand.

It is therefore important that we address this issue through appropriate and sustainable measures. Only then will it be possible for humanity to live in peace in the future.
