A first difference between these two places is the nature. In the country everything is natural, there are a few buildings, up to now it is very difficult to think that they could destroy the ecosistem, because of the miniority ot these constructions in the country side. In contrast, in the cities, it is very difficult to see a lot of trees or a forest area, a fact is that we can see a lot of buildings. As a result, natural areas are reduced, something that really affects our ecosistem.
