The topic is:
The birth rate in most developed countries is predicted to begin fall over the next 50 years. By 2030 it is estimated that over one third of the population in most developed countries will be aged 65 and over. What effects will these predictions have on developed countries if they prove true? What can be done now to deal with this situation?==
Nowadays decreasing birth rate is common among world's richest countries. The situation, triggered by working middle-aged people, who are responsibly planning their parenthood, is predicted to become a huge problem in the future. Some possible consequences and the ways of reducing the negative effect should be discussed.
To begin with, the increasing percent of older people lowers the number of active workers, who maintain the economics. Therefore, in the future the minimum pensioner age is likely to be a lot of higher than it is currently. In addition, many countries will have bigger expenses on medicine, since there will be much more people to take care about. Also, the money matters could become substantially worse for both, younger and older people, as a result of greater funds required for pensions and the decline of workforce.
However, some actions could be taken now to prevent dramatic situation in the future. Firstly, the governments should encourage birth rate by offering decent support and making the decision to have children easier. Secondly, in order to adapt to the rapidly changing environment, people must learn whole life. In this dynamic century it is crucial to understand, that education is not only for youth, but also for elder. Obviously, it is the only way to fight with the ageing of society.
In conclusion, the next fifty years will become a considerable challenge to the most developed countries in the world. The question is how seriously it will be taken before affecting ordinary people.
