Environmental problems in

Environmental problems in urban environmental problems in urban areas and around these are phenomena that stem from the increase of urban growth and resulting in the deterioration of environmental conditions. The change of land use and concentration of natural resource use, are the cause of environmental problems. As a place of population growth, commercial and industrial activity, cities are the energy and resource use and waste generation to the point where both artificial and natural systems are overloaded and the capacities to manage are overwhelmed. This situation is worsened by rapid population growth of cities. The resulting environmental damages or costs threaten the future productivity of cities and the health and quality of life for its citizens.Cities have become the main "environmental red zones" that urgently require special attention in regional environmental assessments and project, and planning and environmental management at regional metropolitan. Systems and urban services (eg water supply, sanitation, public transport and roads) are becoming increasingly congested due to population growth, commercial and industrial, along with poor urban management. Natural resources (water, air, forests, minerals, land), vital to the economic development of cities and future generations are lost or wasted through inappropriate urban policies. Steadily increasing the radius of impact of cities on the resources that are far from its borders. Moreover, urban areas are flooded by their own waste and suffocated by their own emissions as a result of inadequate policies and practices of pollution control and waste management.Many negative impacts associated with the above conditions. The major health risks in many cities in developing countries, yet are tied to the traditional problem of disposing of excreta. At the same time, there is growing concern about the risks to health is due to the modernization of waste and toxic emissions, trauma (traffic accidents and other violent deaths), and urban stress. The spatial scale of these impacts from the domicile to the entire community, urban areas and in some cases the regions beyond. The impacts of even greater concern are often at the home and community, and relate to deficiencies in infrastructure and urban services. The inhabitants of the cities, particularly the poor, support most deteriorated environmental conditions through the loss of health and productivity and reduced quality of life. It raised the costs of resource exploitation (egthe cost of new sources of drinking water) as they run out of resources affordable and high quality. Emissions related to regional and global environmental problems are generated each time in urban areas or as a result of urban demand (eg, urbanization itself could be a major factor in world energy demand over the next generation) .
