Cities may however also have a positive influence on the environment. UN Habitat stated in its reports that city living can be the best solution for dealing with the rising population numbers (and thus still be a good approach on dealing with overpopulation). This is because cities concentrate human activity into one place, making the environmental damage on other places smaller. Letting the cities have a positive influence however, can only be achieved if urban planning is improved and if the city services are properly maintained.
Distinction between cities and towns
There are probably as many different ways of conceiving what a city is as there are cities. A simple definition therefore has its attractions. The simplest is that a city is a human settlement in which strangers are likely to meet. Richard Sennett, The Fall of Public Man, 1977, p. 39.
