So, I considered some aspects of an ecological situation in the cities, and also relationship of the cities with environment. Completely not to destroy a place of the dwelling, the person needs to make thrifty use of environment very much. The ecological situation causes the necessity to estimate consequences of any activity connected with intervention in environment.
The most perspective way of a solution is processing of city waste. The following main directions in processing gained development: organic weight is used for receiving fertilizers, the textile and paper waste paper is used for receiving new paper, the scrap metal goes to melting. The main problem in processing is sorting of garbage and development of technological processes of processing.
