which studies the impact of urbanization on people's lives and the global environment, Mr. Rob
De Jon Director of the section of the urban environment program of the United Nations
Environment had at the publication ceremony said: "Almost half of urban dwellers live in slums
or people lack access to services basics such as water, health or sanitation development.
Approximately 1.6 million people die each year because of drinking water and sanitation, cities
not only play a vital role in sustainable development, but they hold the keys too many problems
s u ch as climate change. "
In fact, a citizen of the community in six lives in a metropolitan area of more than one
million inhabitants, while one in three is a city of fewer than 20,000 inhabitants. In fact, a very
significant proportion of the population live in rural or suburban but travels daily to work in a large
metropolitan area. These movements’ commuters are major sources of air pollution, transport congestion
and noise. The situation is particularly acute in most major southern approaches, where growth has been
rapid, which was accompanied by a significant degradation of the living city. This is where the
demonstration of static officials shows that in 1800; only 3% of the world population lived in cities, 15%
in 1900 and 50% by the year 2000.
In this report, cities are both the biggest threat to the global environment and the main
victims, so it is necessary to give to them to find potential solutions to prevent these threats, he added.
