The passage is mainly concerned with ____ .

Built by the disconsolate Emperor Shah Jahan in
memory of his wife, the Taj Mahal mausoleum has
survived the rise and fall of many empires and it
attracted looters, too; over the years they carried away
the silver doors from its gates, the precious stones
from its marble wall: and the gold from its graves. But
those were small threats compared with the modern
danger of pollution. Emissions from the coal-fired
steel foundries thermal power stations, cars and an oil
refinery in the industrial belt around Agra are
corroding and yellowing the Taj Mahal's white marble.
