As for me I think that Green Belts should be protected. While erecting big city zones people should think not only about urbanization but about the use of green zones as well . A person is a part of nature and we mustn't forget it. What's the use of Green Belts you may ask. First of all Green Belts give us oxygen that is necessary for our planet and for the mankind. Besides that it's a pleasure to have a rest under the trees and go for a picnic on Sundays. Green Belts clean air and keep away dust of towns and cities. People must breath fresh air in order to be healthy.
