The odd-even vehicle scheme is back in Delhi even as the air quality remains ‘severe’in the national capital region amid the blame game between politicians and state governments. On November 4, BJP MP Vijay Goel drove his odd-number SUV to violate the rule in a ‘symbolic protest’ against the vehicle rationing scheme. Of late, there have been many statements by leaders on pollution that stirred an outrage. Health minister Harsh Vardhan’s tweet on eating carrots to fight pollution and Environment minister Prakash Javdekar’s Sunday morning suggestion on classical music invited brickbats on social media. UP minister Sunil Bharala’s suggestion to perform ‘yagnas to please Lord Indra’was also met with heavy criticism.
