Nowadays I find a lot of parents complaining that their children are suffering from asthma. Infact children nowadays are quite adept in using inhalers and nebulisers. I feel the rise in air pollution in the form of automobile pollution could be a reason for this. Green trees have become things of the past and when you step out of your home you only breathe in varieties of dusts  Breathing fresh, pure air has become a luxury now. What is your opinion?
