In the last 100 years, there have been many important discoveries, such as computers, the internet, antibiotics and vaccines. In my opinion, the discovery that has been most beneficial for people in my country, Vietnam, is antibiotics. In this essay, I will explain why.
Firstly, antibiotics have saved millions of lives. Before antibiotics were discovered, many people died from infections that are easy to treat today, such as pneumonia, tuberculosis and infected wounds. Even a small cut could become very dangerous. After penicillin was discovered by Alexander Fleming in 1928, doctors were able to cure these diseases. In my country, in the past, many children died from infections when they were very young, but now this is much less common.
Secondly, antibiotics made modern medicine possible. Today, doctors can perform operations, such as heart surgery, caesarean sections and organ transplants, because they can use antibiotics to prevent infections after the operation. Without antibiotics, these operations would be very dangerous. For example, my mother had an operation a few years ago, and she was given antibiotics to make sure that she did not get an infection.
Thirdly, antibiotics have helped the economy of my country. When people are healthy, they can go to work and earn money for their families. They also live longer, so they can work and contribute to society for more years. In addition, antibiotics are used in farming to keep animals healthy, which helps farmers to produce more food.
However, people should use antibiotics carefully, because using too many antibiotics can make them less effective.
In conclusion, I believe that antibiotics are the most beneficial discovery of the last 100 years for people in my country, because they have saved many lives and made modern medicine possible.
