i sadly have to say… the air in bangalore has become worse than in delhi…. being in a traffic jam in bangalore seems like getting sufficated, one reason might be that all the public transportation in delhi runs on the CNG (gas) and this is not the case in bangalore where you can see dark clouds of dirty smoke polluting the air. but being in a traffic jam here in bangalore just sucks big time… also i personally find delhi much greener than the “garden city”… it would really do some good to plant some more trees here again to fight the pollution in bangalore
