The Indian capital of New Delhi is covered with dangerous smog.The situation has closed schools and forced officials to consider declaring a lockdown--a stay-at-home order.Pollution in New Delhi has reached severe levels on several days this month.Officials have ordered schools and colleges to close and ordered people to work from home in an effort to control the pollution.Six power plants in the city were also ordered to close temporarily.The federal government has also banned construction until the end of the week.It has also barred trucks from entering the city, except those carrying important items.Environmental experts note that these steps would only partly help the air pollution crisis that troubles New Delhi every winter."The emergency action is not a magic bullet that will address the pollution crisis," said Anumita Roychowdhury.She is with the New Delhi's Center for Science and Environment.The steps "will not worsen the pollution but it will not clean the air," Roychowdhury added.New Delhi is the world’s most polluted capital city.It has recorded levels for dangerous particles, known as PM 2.5, many times higher than normal levels.
