It was heard for several years that Taj Mahal made of white marmalade has become yellow, now the unique structure is gradually becoming brown and greenish! The Supreme Court of India has expressed concern over this.
The bench, comprising Supreme Court judges Madan Lokur and Deepak Gupta, directed the Indian government to assist foreign experts in solving this problem on Tuesday. The court directed the Indian government to examine the picture submitted by environmentalists. 
The court criticized the government and said, 'If you are an expert, you are not using them. You are not giving importance to the matter. "The Supreme Court will again hear on May 9.
Prior to keeping this Taj Mahal's color correct, the Indian government had ordered the closure of many industrial areas.
According to the BBC report, the color of the Taj Mahal is changing for three reasons. The reasons are, insecticides, oil refineries near the Taj Mahal and a cremation ground of over 200 years old. Alongside, a shopping mall in the Uttar Pradesh government near the Taj Mahal is responsible for this problem.
The BBC report also said that the part of the Yamuna river which was adjacent to the Taj Mahal is very contaminated. Perhaps the impact of this pollution is directly on the Taj Mahal. The Indian government often clears the river related area. The river has been cleared once in January. Apart from this, clay plaque was given to the wall of the Taj Mahal to prevent yellowing. But nothing was done in the work.
Every day 70,000 domestic and foreign tourists are crowded there, to see this unique pattern of the seven wonders of the world, Mughal Emperor Shahjahan built this beautiful mausoleum for the memory of his wife Mamtaz. Standing on 42 acres of land, this unique structure is located in Agra, India's northern province of Uttar Pradesh.
