उत्तर
Large amount of carbon-dioxide in the polluted air results in increase of greenhouse effect which has raised the average temperature of the Earth by 2°C. This results in global warming which, in turn, will melt ice on the polar caps, thereby raising the level of sea water by a few metres. This can result in submerging of coastal areas and islands causing excessive damage.
