Question

In the 1970s, the effect of air pollution on the monument began to be noticed. It was caused by local industries using coal and other fossil fuels, which left a yellowish tinge on the marble. Following the recommendations of an expert committee and a PIL in the Supreme Court, a ban was imposed in the mid-1990s

Answer 1

This observation about the Taj Mahal shows how environmental pollution can damage important historical monuments. The yellowish colour of the marble is mainly caused by pollutants such as sulphur dioxide released by industries, which react with the marble and form yellowish substances. This example highlights the need for laws and public efforts to protect cultural heritage, as well as the important role played by the Supreme Court in protecting the environment and historical monuments.
