does pollution in large cities affect human health? Pollution‚ a worldwide problem which has been concerned with since 1972 (Seitz 2008:156)‚ has significant effects on human health in large cities. It may be defined as several different types of pollutant in environment mainly caused by industry and agriculture‚ having a harmful impact on public health. It is because cities‚ most of which‚ have depended on the two types of industry to develop the economy that the problems of urban pollution are

INTRODUCTION Air pollution is define as the presence of chemicals in the atmosphere high enough to affect climate and harm organisms and materials. Gaseous or particulate substances released into the atmosphere in sufficient quantities or concentrations to cause injury to plants‚animals‚ or humans. Other sources of pollutants included dust and fine particulate‚ which were contributed by the inefficiency of diesel-powered vehicles and also the smoke aerosol from fires on Peninsular Malaysia.

As we are all aware reducing the amount of fuel consumption has turned into a controversial discussion for the past 2 decades. I personally am of the belief that increasing petrol cost is not the only solution to resolve the traffic issues and inevitably‚ governors should choose alternative parameters to decrease the potential causes of such difficulties. Living in the 21st century has increased people`s tendency to use their private cars excessively in comparison to the past‚ chiefly because

policies largely influence the way humans interact with the environment. Policies targeting air quality‚ namely the Clean Air Act‚ have been effective in lowering the emissions of pollutants; however climate change is still something that concerns some scientists‚ citizens‚ and policymakers. As such‚ the need for further progress is necessary. In order to make such progress policymakers may need to develop air quality and climate change policies through an integrative approach. Doing this‚ however

AIR POLLUTION Air Pollution is another major problem that is yet to be solved. The air is 99.9% nitrogen‚ oxygen‚ water vapor‚ and inert gases. We as humans depend on the air around us to live‚ without it we would die. Although we rely on this as an essential source for living‚ it is still littered and polluted with chemicals. Pollution of the atmosphere and the air around us is air pollution‚ and this is becoming more "popular" everyday. There are several main types of air pollution that include

ENERGY RESOURCES Energy is defined as ‘the capacity to do work’. Sun is the primary source of energy. Joule is the standard unit of energy in SI units. Energy utilization is an index of economic development‚ which does not take into account of ill effects/damage on to environment. From 1900 to 2000 population increased by 3 times while energy consumption by 14 times! Energy Resources All energy sources ultimately come from the sun‚ the moon or the earth.

Air pollution is one of the virtual problem nowadays. There are many reasons of it but mostly it is caused by cars‚ growing cities‚ development of economy and industrialization. Clean air consist of several gases. When some other gases or dangerous elements get into the clean air‚ pollution is inevitable. Ozone layer is affected too much by pollution and it will cause serious disturbances on the environment. People are the main cause of pollution because the things that we use contain dangerous

Air pollution Air pollution is a problem everywhere in the world. Local air pollution usually affects big cities. Air pollution becomes a worldwide problem when local pollution moves away from where it came from. For example‚ winds carry air pollution made in the middle of the western part of the United States to Canada‚ like acid precipitation. Acid precipitation Acid precipitation is precipitation‚ like rain‚ sleet‚ or snow‚ that contains acids from air pollution. When fossil fuels are burned
