Environment in Cities
Urban pollution in big cities and towns is one of the most important because it directly affects millions of people have an impact on the health and quality of life.
Environmental problems in urban areas and around this is a phenomenon that comes from the increasing urban growth and resulting environmental degradation. Changes in land use, and the concentration of the use of natural resources, is the cause of environmental problems.
It is for this reason that the urban system imports a large number of resources are transformed into goods and services and partly back into the environment as wastes and emissions.
Urban environmental problems affecting the real urban environment, but also to other regions of extracting resources and achieve the effects of pollution.
Cities that are installed on natural ecosystems is fully modified, the result of technological advances that have been achieved humans. In this ecosystem, landscape modification is complete. Original matrix is replaced with a cement covering the soil with the changing relationship between infiltration and runoff of rainwater and reduce the movement of nutrients, natural habitats have been replaced by buildings and native biodiversity has been replaced by a species, humans. This system is not able to produce for stock requires the supplier system: the natural and productive and unable to digest the waste they produce, have to use another room to dispose of their waste.
Activities conducted in urban or urban-industrial and rural areas, which could include agriculture, animal husbandry, forestry, etc., Generate various types of waste that can be a pollutant and cause environmental problems and therefore both affect the quality of living of its citizens.
I could mention, among others:
1. Generation of solid waste from homes, businesses, service companies, public institutions (health, education), industry, sweeping streets, among others.
2. Generation of wastewater from homes, businesses, industries, and rainfall.
3. Gas emissions from vehicles, incinerators, furnaces and industrial.
4. Noise generated by vehicles, recreational center, industry, among others.
5. Electromagnetic pollution.
Among all the elements that pollute the city, private cars are the object produces the greatest impact. Pollute the air with the combustion produces an excess of noise, and occupies a large amount of space, causing congestion and mobility problems for pedestrians. You also need the infrastructure to operate, which is also, in itself, pollutant: paved roads.
Cities grow at the same time they do the problems caused by noise, pollution, desertification impacts of climate change. In the twentieth century dreamed of an ideal city park, a proposed union between urban and rural areas. However, large cities have been growing rapidly. It also must overcome the problems the new environment.
For this reason, the garden city concept was no longer realistic and the city should transform itself to become a little more green and sustainable.
