(i) Burning of wood gives a lot of smoke which is very harmful for human beings and it causes respiratory problems also hence it has been replaced by other pollution free fuel.

(ii) Sulphur dioxide and nitrogen dioxide are emitted by burning of fuels in Mathura oil refinery and other rubber processing, automobile chemical industries working in and around Agra. When these oxides of sulphur and nitrogen mix with rain water then acid rain is caused. This acid rain corrodes the marble of Taj. Due to this, colour of white marble has started to fade.
