The Time magazine has included two Indians—Sunita Narain and Bhure Lal—on its list of six Climate Crusaders of the world, for fighting pollution. Narain, head of the Centre for Science and Environment and Lal, Chairman, Environmental Pollution (Prevention and Control) Authority, worked towards building the world’s cleanest public transport network, the magazine said in its latest issue. Delhi now has nearly 15,000 buses, more than 12,000 taxis and over 80,000 autorickshaws.It is because of their effort that Delhi now has its public transportation system, mainly bus, autorickshaws and taxis, being run on the environment-friendly CNG, Time noted. As a result, air pollution in Delhi has stabilised, it said.Before CNG was brought in, Delhi was considered to be the fourth most polluted cities of the world.
