Smog fills our city, but luckily not in huge extent. This picture was taken from the roof of a mall. I chose a new option on my camera.
The main cause of air pollution is I guess the huge number of cars and traffic jams. I think public transport is the best solution for this problem. I use it all the time. That’s all folks:)
I agree with your idea, but not all public transportation vehicles protect our environment. Think of buses or troley buses. They exhaust a lot of fumes into the air.
