It is predicted that the percentage of elderlies will be more than that of younger ones across the world in the future. While this prediction might be beneficial, I consider that this development is disadvantageous.
It cannot be denied that the higher proportion of old people can bring certain benefits. When there are a lot of elderlies, the world will have more experienced people, leading to better innovations and decisions to improve future life. Another advantage is the safety in locations across countries. If people are older, they would commit less crime as the courage to do crime is decreases with age due to lack of physical energy. These are one of the main advantages of that prediction.
Nevertheless, there are several downsides of this development. The old might bring more pressure on healthcare systems as elderly require more medical treatment to keep them healthy. As people get older, their immune system will be damaged and to keep that people often use antibiotics and other treatments. Equally disadvantageous can be the fact that the economy will suffer from the high pressure. If the number of old peoples will increase, a shrinking workforce must financially support a growing retired population, which can create significant economic imbalance. These are only a few of many drawbacks of that prediction.
In conclusion, even though there are several advantages of high portion of elderlies such as knowledge and safety, the advantages of this trend like demand for medicine and the economical burden are more significant.
