Pollution 'killing' India’s iconic Taj Mahal
India's most famous monument, the white marble Taj Mahal, is "dying" -- according to historians and local guides who are calling for the government to protect and carry out preservation work on the palace. Pollution in Agra, which has risen sharply over the past 30 years, has been blamed. The city, which sits on an industrial belt, is ranked eighth in the world for the most polluted air, according to a World Health Organization list earlier this year. The iconic 17th century Mughal palace, built by Emperor Shah Jahaan in memory of his beloved queen Mumtaj Mahal, is visited by millions every year, including royalty and film stars. But local guides say foreign tourists are dwindling because of the pollution that is lending a yellowish tinge to the walls of the Taj Mahal.
