Describing the crisis as preventable yet worsening, Dr GC Khilnani, Member, Advisory Council, Illness to Wellness Foundation and Chairman, Institute of Pulmonary, Critical Care and Sleep Medicine, PSRI Hospital, cautioned: “Air pollution is a man-made public health emergency that has already reduced the average life expectancy of Indians by several years. Its most dangerous effects are often invisible—ultra-fine particles penetrate deep into the lungs, enter the bloodstream, and damage multiple organs without early warning signs. While governments are taking steps, real change will come only when society recognises its own role in this crisis,” he said.
