Problem Reasons Opinions and suggestions
Problem Reasons Opinions and suggestions
Possible answer:
Many young people want to leave the countryside because they want to find jobs in the city.
This is a big problem for the countryside and city. More and more young people crowd into cities, so there are few people working in the countryside. Meanwhile, there are so many people in the cities that some may not find a job.
It may be better to build more universities and create more job opportunities in smaller towns in the countryside, so young people will find it more interesting to stay.
Problem Reasons Opinions and suggestions
Too much traffic brings air pollution.
This is a national as well as an international problem. Governments in every country do not do enough to control traffic pollution.
The governments should develop public transport so that people do not use their cars so much in the big cities.
