It is true that while the average age is rising globally, the birth rates show an opposite trend birth rates are less than that. So (문장을 and but so 로 시작해서는 안 됩니다.), more and more people are concerning about emerging the emergence of different issues. Even though there are some positive impact on societies and families, I would argue that this phenomenon leads to more serious results on our communities.
There are two main advantages for seniors to that seniors can give their families. First of all, they can support their families emotionally. In contemporary society, working parents are sharply growing up, as a result of it, their children can not be protected from a variety of violence and crimes so an adolescence crime rate goes up. (이 문장의 경우 중간 생략이 너무 많이 되어있기 때문에 가운데를 채워주셔야 합니다. 예를 들면, 맞벌이 부부가 증가함에 따라 '아이를 돌보거나 적절한 도덕 교육을 시킬 시간이 없기 때문에~~~' 등의 사항이 필요하겠죠.) Therefore, the elderly can have an important role to prevent this problems by staying and taking care of their grandchildren at home instead of double-income parents. Additionally, since jobs for the old has an upward trend since more there are more job opportunities for the old, they can manage their life economically, in other words, it can reduce the burden on families who need to support to the elderly.
Despite some positive effects as I mentioned above, I believe that graying has seriously negative impacts on both individuals and societies. To begin with, in terms of individuals, an increasing old population and a decreasing birthrate cause a fall of productive workers and willingness to produce because of the burden on tax revenues which will be spent for the elderly. On top of that, when it comes to the societies, governments should spend a large amount of budget on senior pension and health insurance. And (여기도 문장의 첫 단어가 and but so 가 되어서는 안 되기 때문에 수정이 필요합니다.) administration might lose young and specialised workers, as a result, suffer from slow economy development.
In conclusion, the population aging would not encourage young people to produce effectively in their workplace, which results in economic recession around world.
