URBAN CONGLOMERATES : 

URBAN CONGLOMERATES Enrico, Marco, Gianmarco – 4CM – Itis Pininfarina

The primitive human groups did not live in fixed places; they transferred from site to site looking for water and food, until they began to cultivate the ground, activity that demanded to settle down, at least, temporally.The possibilities that agriculture offered, the necessities of the organization of available resources impelled them to group into conglomerates. Thus the city arose like an isolated population centre in very vast and depopulated territories. : 

The primitive human groups did not live in fixed places; they transferred from site to site looking for water and food, until they began to cultivate the ground, activity that demanded to settle down, at least, temporally.The possibilities that agriculture offered, the necessities of the organization of available resources impelled them to group into conglomerates. Thus the city arose like an isolated population centre in very vast and depopulated territories.

The medieval cityDuring the Middle Ages, the cities were built around feudal castles. But as the urban centres grew thanks to the economic development, their inhabitants associated to defend their rights and to obtain political privileges. In those traditional cities, the houses were built very close, with very narrow streets and a central square where the commerce was concentrated. The squares were populated by independent craftsmen who gave origin to a new social class, denominated bourgeoisie.The technical improvement, the increasing necessity of manual labour in the industry, the progress of medicine and the creation of public transport determined a vertiginous development of the urban conglomerates. In 1800, 50 million people lived in cities; in 1994, 1,500 million. :

The problems of the great cityUnfortunately growth carries enormous disadvantages. The quality of life in the cities has been deteriorated seriously.Overpopulation, deficient elimination of rubbish and pollution – both from industries and from the circulation of vehicles - turns the great cities into the main centres of contamination of the planet. : 

The problems of the great cityUnfortunately growth carries enormous disadvantages. The quality of life in the cities has been deteriorated seriously.Overpopulation, deficient elimination of rubbish and pollution – both from industries and from the circulation of vehicles - turns the great cities into the main centres of contamination of the planet.

Contamination The cities consume enormous amounts of energy and resources, and daily generate tons of industrial and domestic waste. The common procedures for its elimination have been the spill in rivers and seas, the burial to fill up low lands and the incineration. In almost all the underdeveloped countries waste is eliminated in that form. Nevertheless, they are highly polluting practises.A special problem is presented by those materials that cannot be decomposed quickly by the action of alive organisms, like bacteria. Certain detergents are non-biodegradable, the same is for plastics and the majority of pesticides. These materials last for a long time, it is very difficult to recycle them and, on the other hand, if we incinerate them they generate dioxins, a compound of great toxicity. This problem could be solved by using new auto-degradable plastic and increasing the use of recycled elements. :
