Living in the city has a lot of pluses. Shops, schools and hospitals are not far from your house. Your friends and relatives can easily get to your place by bus or on foot. You can never be absolutely alone in the city with so many people around you all the time. Yet living in the city has some bad sides too. One of them is pollution. Thousands of cars and public transports pollute the city's air. Another bad side is a lot of noise. Street noise, noise coming from your neighbours do a lot of harm to our nerves. Fresh air, beautiful quiet landscapes can hardly be found in big cities.
