A judge of the Supreme Court said: even if the government has expertise in this field, it has not been used, or is simply not concerned about this problem. According to the Supreme Court, the mausoleum built in seventeenth Century, with white marble and other materials, is now yellow, even green and browning. Pollution, construction and insect feces are thought to be partly responsible for the discoloration of Taj Mahal. India Supreme Court judge Madan Lokul and Deepak Gupta reviewed the Taj Mahal photos submitted by environmentalists and subsequently asked the government to seek the government from home and abroad to repair the Taj Mahal. Indias government has previously closed thousands of factories near Taj Mahal, but environmental activists say that even so, Taj Mahals marble is still fading. In addition, the sewage discharged into the vicinity of the Taj Mahal in the vicinity of the Taj Mahal also spawned insects. Their excreted feces left spotted stains on the walls of Taj Mahal. Taj Mahal, located in the city of Agra, India, was ordered by the moghal emperor Shajahan. It is one of the most famous scenic spots in the world and attracts more than 70 thousand visitors every day.
