World Heritage List: does it make sense?

The UNESCO World Heritage List contains the 900 most treasured sites of humanity's culture and landscapes. This List is beneficial where heritage sites are undetected, disregarded by national decision-makers, not commercially exploitable, and where national financial resources, political control, and technical knowledge for conservation are inadequate. Alternatives such as market and national conservation lists are more beneficial where the cultural and natural sites are already popular, markets work well, and where inclusion in the List does not raise the destruction potential by excessive tourism, and in times of war, or by terrorists.
