Dear all,

 we are facing the problem of pollution that we have facing air pollution, nose pollution and water pollution may be in banglore city as large number of people in there city in these days

This is largely due to high numbers of vehicles in congested urban areas and the quantity of pollutants they emit, causing various adverse effects.
Vehicles discharge emissions directly into the breathing zone; motor vehicles possess the greatest air pollution potential as compared to other sources.
it has been generally established in earlier studies that about 60% of the air pollution in cities is due to automobile exhaust emissions.
Most of the metropolitan cities are facing serious air pollution problems due to concentration of motor vehicles and human population within the confined urban areas.

Further, limited road space leads to road congestion and poor road surface conditions significantly add to pollution problems.
