Describe a serious problem in your city/hometown. you should say: -what it is -what has caused this problem -what can be done about it -and explain why you think it is serious (краткое сочинение о проблеме маленького города)

In my opinion, nowadays, a large number of towns have many problems.
I think, that most important problem is environmental pollution. 
Private entrepreneurs builds factories, industrial centers and this improve level of pollution. In our time almost everyone has a car which also adversely affects the nature.
The second most important problem is lack of jobs. A lot of people can have a job, they are forced to survive.
For this two problems authority must pay attention and take some measures, for example:
- Increase the number of jobs;
- Increase salaries;
- Prohibit mass use of cars in the city;
- Install filters in factories.
With this measures towns will flourish.
