उत्तर
Vehicles and factories are the major sources of air pollution. If the number of vehicles and factories increases in our surroundings, it is obvious that it would result in increased levels of air pollution. Not only air pollution but they also result in noise pollution. In case the number of industries increases in our surroundings, it means more trees would have to be cut down to make way for them, thus resulting in damage to the environment.
