The Pros and Cons of Science Inventions
Science and invention have led us to a more convenient daily life, but are they always good? We should look at both sides of the coin. So I am writing to discuss the pros and cons of science and invention. First of all, with science and invention, there will be less work for human to do. Also, it will be more effective in doing some complicated work. This makes humans’ lives more enjoyable. Vacuum cleaner is a good example, it can remove dirt and dust from the floor, and it is very helpful for housewives. Vacuum cleaners are also important to those who suffer from allergy and asthma, because high- temperature vacuum can sterilize bacteria while working. Furthermore, with scientific invention, we can discover new treatments for diagnose problems. For example, for those who suffer from diabetes– a disease which is becoming increasingly common, now have access to very accurate blood glucose monitoring technology. This means that they can monitor on a daily basis and control their condition much more effectively, sharply reducing the risk of blindness and nerve damage. However, there are, of course, some disadvantages along with the development of science and invention. Inventions are not always good. Sometimes, they may make people become lazier and less capable of doing things for themselves. This is because they rely more on machines and products. Nowadays, many people are addicted to computers and mobile phones. This results in a lack of imagination of kids. Also, they don't know how to solve problem on their own. If they look at the screen for a long time, they will get short-sighted, too. Another important argument is that science invention may be used to create some dangerous weapons and bombs that is harmful to the society. They can kill people and cause environmental destruction. For example, the atomic bombs that were dropped on Hiroshima and Nagasaki at the end of World War II had caused a great damage to the people and environment there.
