Taj Mahal
Many people think the Taj Mahal is one of the most beautiful buildings ever built. However, it is slowly being damaged by acid rain in the nearby Yamuna Basin. A nearby oil refinery has been blamed for some of the damage. In 1996, the Indian Supreme Court said that local industry was harming the Taj Mahal. The court set up an area of 10,400 square metres around the Taj Mahal called the Taj Trapezium Zone. Industries within this zone must use natural gas instead of coal.
