Now to India, which has the worst air in the world. That's according to a new environmental study by Yale and Columbia. Here's Ajoy Bose from New Delhi with the story.

Ajoy Bose:
It did not take long for Twitter to be buzzing about the grim news. One tweet warned that the "alarming news put at risk the health of the people and economic development." Quite a few tweets blamed the huge spurt in car ownership across India for the increased pollution. There has been also fierce discussion on the topic in various blogs and web sites. One comment urged people to use bicycles instead of motorcars or scooters for private transport. Another felt that more trees needed to be planted for India to get healthy. Not surprisingly the alarm over pollution has sparked off severe criticism of the government. One comment pointed out that the government had remained a "mute spectator" during the Bhopal Gas tragedy 28 years ago. The industrial accident killed several thousand people and sickened many more. Such a government, said the commentator, could hardly be expected to check the fumes coming out of factories doing business-as-usual. Another raged against municipal governments who did not bother to check either vehicular pollution or trash burning. A third, perhaps reacting to the pollution official's "non-issue" remark, said he wasn't surprised -- bureaucrats were too busy looking after their own well-being and taking bribes. While some comments bordered on extreme despair, there was at least one person who felt that instead of blaming the government, it was better to take your own measures to lead a healthier life. He pointed out that had moved two years ago from a city to a semi-urban area where, apart from cleaner air, everything was better. For LinkAsia, I'm Ajoy Bose in New Delhi.
