How science and technology have helped population growth

How science and technology helped population growth is a popular question that many technology enthusiasts ask worldwide. Science and technology have been evolved beyond our imagination. Everywhere we go, we are surrounded by science and technology.


The great inventions that science and technology have provided the world have helped people in numerous ways, including population growth. Many of you might not be familiar with how science and technology helped population growth, and that is why today, we are going to discuss all of it.

How science and technology helped population growth? – Reasons

There are numerous reasons why science and technology have played a significant role in increasing the human population. Some of the most popular ones are specified below.

  • Medicines
  • Vaccines
  • Medical devices
  • High-quality food
  • Less human efforts
  • Carbon capture technology
  • Clean drinking water
  • Medicines

Before science and technology took off, people used several herbs to cure their disease. These were not very effective, which caused many people to die even due to the most common diseases like diarrhea and common flu

However, in the 19th century, medical science rapidly took off and created medicines that could treat common diseases like flu. As these common diseases were cured successfully, the human population grew, and the mortality rates became low.

Since then, many medicines have been made that are more advanced. That is one of the reasons due to which science and technology have aided in population growth.

  • Vaccines

When science, particularly medical science, was not evolved, people died due to common infections such as colds and fever. You may be shocked to hear, but in the 18th century, common flu was the leading cause of death worldwide.

However, as time passed, medical scientists did some research and made a significant breakthrough. They came to know about antibodies, what they are, and how they help our bodies fight infections and numerous diseases.

Since then, scientists have made various vaccines and antibiotics. Vaccines prevented people from catching various infections and diseases, like Poliomyelitis, Influenza, and many more. Not only this, but vaccines also helped to reduce the complications related to the diseases.

It enabled people to live longer as compared to before. Thus, it is one reason why science and technology helped population growth and significantly lowered the mortality rates.

Antibiotics were also made, which were used to treat the already present infections and diseases in the human body. The most important part is that most of the vaccines and antibiotics are still being used, and without them, the mortality rate would have been much higher.

  • Medical devices

If we look back at the 18th and 19th century, there were no proper medical devices to detect a disease or an infection. It caused many people to be unaware of the fact that they had numerous health complications. Hence, this caused a drastic decline in the human population.

However, as science and technology evolved, it produced medical devices such as CT Scan Machine and X-ray machines. All of them were able to detect infections and numerous problems in the human body at the earliest stages.

Detecting the infections and diseases gave doctors a chance to cure patients at the earliest. Hence, this is one of the many reasons how science and technology helped population growth.

  • High-quality food

Due to the improvements in science and technology, scientists were able to study various agricultural lands. Scientists identified what crops should be grown on specific land and what should be avoided.

Moreover, scientists also developed numerous fertilizers, which helped many farmers improve the quality and the number of their crops.

All of this helped people to consume high-quality food, which significantly improved their overall health. Hence, this lowered down the mortality rates and people lived longer than before.

Besides this, in the last 10 – 20 years, scientists found a way to develop numerous pesticides and herbicides. All of these contributed to healthy crop growth. Due to the consumption of healthy crops, people could develop fewer infections and were immune to several diseases.

Hence, this is one of the most vital reasons for how science and technology helped population growth.

  • Less human efforts

Due to the rise in technology, scientists were able to several machines that mimicked human movements. However, these movements were not the same, but they saved humans from the extra effort.

For example, previously, when machines were not invented, people working in coal mines had to do all the work by themselves. Both the harsh environment and the efforts reduced the life expectancy, which caused the human population to be drastically reduced.

But since engineers have mechanized the majority of the process, the safety of the miners has significantly increased, and this has increased their life expectancy. Hence, this is one of the reasons how technology and science helped population growth.

  • Carbon capture technology

Previously, when science and technology did not make any significant improvements, mortality rates became significantly higher because of the drastic change in the climate. Due to the industrial revolution, many factories were been set up. This meant more carbon emissions. Hence, as people inhaled more carbon, their life expectancy drastically reduced.

In the last couple of years, the rise in technology has aided scientists in developing carbon-capturing and storage technology, which reduced the greenhouse effect, and has radically reduced the pollution from the air. This has also caused the climate not to become too hot, which has also helped the human population.

  • Clean drinking water

Due to the improvements been made in technology, scientists have developed numerous filtering techniques due to which areas where there’s no fresh water, like Eritrea, Uganda, Ethiopia, can get access to fresh water. Clean drinking water means a lower mortality rate.


The above-specified are some of the ways which will help you know how science and technology have helped population growth. It has really changed the numbers worldwide. It is also important that we believe in using technology in a fair way as if we overuse it, things can turn bad for people too. So, always have benefits of technology by using it sincerely.
