For the second time this year, a million New Delhi cars will be forced to stay off the road each day for the next two weeks in an effort to reduce the city’s hazardous air pollution levels.
The Indian capital was ranked the world’s most polluted urban center in 2014, with smog concentrations frequently reaching hazardous levels for children, the elderly, and people with heart or respiratory issues. The Delhi decision follows a similar recent driving ban in Mexico City, where heavy smog and high ozone levels have also raised health concerns. But some scientists argue that such bans are insufficient to combat escalating pollution problems in developing world megacities. “It is exactly like taking out 10 buckets of water from the ocean, the magnitude of the pollution problem is such,” Gufran Beig, the chief scientist at India’s state-run System of Air Quality Weather Forecasting and Research, told The Guardian.
