Smog has begun settling over Norway's scenic Geiranger Fjord, which recently won a spot on the United Nations' "World Heritage" list. Emissions from the stream of larger and larger cruiseships sailing into the fjord are being blamed.
The quiet fjord tightly surrounded by high mountains can be especially vulnerable to air pollution, and smog has been forming of late like a grey-blue lid over the otherwise pristine area.
Results show that one of Norway's most popular tourist destinations, and one often featured in promotional materials, can have air quality that's on par with London or Glasgow.
Tourism officials are concerned over the consequences of the very tourism they've been promoting, and not just because of the potential environmental damage.
