Polluted air could cause long term breathing disorders like asthma. On the other hand, modern life of people would collapse and they might have difficulties in their daily routine.

By doing small step against air pollution, would help for non air polluted universe in future. Moreover, people should use public transport rather keeping leg on private one.
To conclude, air pollution must reduce in the world so that we could build a bright future. Personally recommend individual measures against air pollution. If people change their way of life slightly to reduce pollution, we would stop air pollution more easily as the proverb says that ‘Several drops make an ocean. “
