Air pollution in Delhi has rose up to hazardous level with air quality index crossing 500 in many areas. But unlike other polluted cities (like Beijing), Delhi has no shut down of schools and businesses. Such a shut down would not only prevent people from its hazardous effects but also reduce pollution levels due to closed industries and less vehicular traffic. So why does this not happen? What are other possible solutions to protect people from this hazardous situation.
Delhi has acute pollution issues once a year during the time farmers around Delhi burn the waste after the crop has been harvested, this combined with adverse wind directions or weather conditions makes the problem worse. The major part of the problem come from outside Delhi rather than within Delhi, banning stubble burning would and should IMO to a large extent help in reducing the pollution. Agreed that Delhi's AQI isn't great even without all the stubble burning but those problems require long term policy decisions such as moving towards BS-VI fuel, CNG powered public transport, electric vehicles and regulating polluting industries.
Because is no system in place to do so. There is no regulation. There are no Public health warnings.
Arbitrarily, schools might be shut down either by their own choice or by government under public pressure.
Sadly, this is the state of most Indian cities. On the other hand, if there is a parents association and it declares that they wont vote for the current government in next election, only then would some action will be taken.
One way is to replace polluted by air by clean air..Hence growing plants and saplings and nurturing them into trees. We have to start at our own place, before saying where is the space to grow it..Thanks.
