Reducing Pollution

Pollution is on a very high raise these days. But nobody ever makes a conscious effort on their part towards reducing pollution. Due to heavy traffic, I observed that at most of the big traffic signals, we stop for at least two minutes. W.H.Y. can't we switch off our vehicles at such junctions which might be some sort of avoidance of noise and also air pollution. On an average 150 to 200 vehicles stop at each RED signal. And I have tested and tried switching off the vehicle and starting again at GREEN. It does not take even 3 to 5 seconds to restart the vehicle. By practicing this type of exercise, we indirectly even give chance to our vehicle engines to cool for a while and also reduce the pollution (air and noise) at the same time. So, my sincere request to all those who view and read this posting to practice this exercise and lets work towards a cleaner environment. By the way, this will increase our vehicle's fuel efficiency too....!!!!
