Every country that has cleaned up its polluted air, has done so after reaching a tipping point. That point has come after pollution has become undeniable, and its health hazards have been acknowledged, after people have realised that existing environmental laws have been de-fanged by industry or lobbies with commercial agendas.
Whether it was Mexico, Los Angeles, London or China, change came after the tipping point was breached. India is at the cusp of that tipping point. With the Aam Aadmi Party (AAP) having brought the issue of pollution to the centre stage, and the BJP and Congress joining the debate (with the BJP tweeting a video recently, squarely blaming the AAP), the pollution debate has finally entered the Parliament.
