The precautions to reduce pollution or the traffic load other than planting trees and waste management can be taken in various levels. As cars and other old vehicles are the ones emitting harmful chemicals and smoke, trolley buses are one of the best option to control both the pollution and traffic load. Increase in the number of cycles also can reduce air pollution. But the condition of the roads, the dust and the smoke only discourages the bicycle riders.
