2009 Urban Environmental Problems
11 June 2009 | Green News | 1 Comment
Environment is one of the three pillars of sustainable development.Human activity has accumulated problems that have left increased pollutants in the atmosphere, vast areas of land resources degraded, depleted and degraded forests, biodiversity under threat, increasingly inadequate freshwater resources of deteriorating quality and seriously depleted marine resources.
Cities contribute substantially to the above problems.In parallel, the other two pillars of sustainable development, social and economic, face extremely important problems, especially in less developed cities.In a general way, the urban environmental problems may be summarized in three main groups: the over-consumption of energy and resources that exceed their production by their nature, the production of degraded energy, waste and pollution more than the assimilative capacity of the ecosphere, and the lack of the necessary infrastructures to ensure the health and well being of all citizens in cities of less developed countries.
Over consumption of resources, mainly energy, associated with increased air pollution mainly from motor vehicles, increases in the ambient temperature because of the positive heat balance in cities, heat islands, noise pollution and solid waste management seem to be the more important environmental problems in urban areas of developed countries.In parallel, poverty, increasing unemployment, environmental degradation, lack of urban services, overburdening of existing infrastructure and lack of access to land, finance and adequate shelter are among the more important environmental, social and economic problems in cities of less developed countries.

Hey, nice post, really well written. You should blog more about this. I’ll definitely be subscribing.
