New Formula

 Pollution in and around Delhi is a serious problem. But the state government's decision to permit only even and odd numbered cars to ply on alternate days is illogical. This would persuade people to buy another car, resulting in a minimum of two cars in every household. What the government needs to do is to build a robust public transport system. Banning cars that are more than 15 years old is not enough. Instead, strict pollution checks should be instituted. The NGT's decision of banning the registration of new and 10-year-old diesel vehicles is a step in the right direction. School and college students should be asked to use bicycles instead of motor vehicles. In certain Indian Institute of Technology campuses, even professors are known to use bicycles, which is praiseworthy.
