The effect of climatic island heat is given in large urban centers, but why? It is a question that can be answered if we carefully observe the social dynamics that develop in denser urban centers, we have transport systems Mass, adding to the population that acquires cars or motorcycles to mobilize, the ecxeso of urbanization and growth of the industry inside the big cities forcing them to undergo to the scenes of pollution and dense clouds that not having sufficient capacity of sinks within those Cities can not leave this space, provoking a "greenhouse zonal" a climate change minority that produces hotter days and cooler nights.

These climate focuses on cultural dynamics that change within cities, higher construction for more people, production of more garbage that affects the city more, more electrical requirement for heaters and air conditioners.

That is why cities must comply with agreements such as the paris agreement or the C40 agreement on climate-friendly cities, preserve areas of environmental importance or, if necessary, the RAMSAR zones as these are the opportune opportunities for ultra cities Contaminated can maintain and in the future achieve to reduce both their air pollution and the effect of heat islands, especially in areas with excess industry or focused on mining.

Making the call to action against deforestation is point more, to avoid the increase of these zones and adverse effects.
