Some problems in Japan
It is important that each person thinks about this problem and tries to solve it. Especially, students must work and support old people in the future or the problem becomes worse. I think that most people know about it but do not think about solving the problem deeply.
Recently, we can get some data easily so we can know and think about problem of the population. Every person thinking about the problem will become the starting point of solving this problem and making society good.
