Nowadays lots of young people tend to move to cities in search of better life. on the contrary, many adults consider such a lifestyle quite dangerous for their children. who is right? is the life in the city really as harmful as it may seem?     on the one hand, city life has lots of advantages. for example,it is often easier to get prestigious education and to find a well-paid job. besides, there is a wider choice of shops, sports facilities and health centres. what is more, if you live in the city, you can eat in good restaurants, visit museums, and go to theatres or con­certs. all in all, city lifestyle is full of variety so you will never feel bored.     on the other hand, we must admit that city life is rather un­safe as there is a lot of crime and violence. what is more, transport and industry are the main reasons for all kinds of pollution there­fore city dwellers often have more problems with their health. last of all, young people living in cities are likely to acquire such bad habits as smoking, drinking alcohol or even taking drugs.       in conclusion, i think that city life has its pros and cons. however, if we try and solve the problems of crime and pollution, then living in the city will be really enjoyable. as for me, i would prefer to live in the city because i am keen on visiting theatres and don't mind noise and pollution.
