|Iguazu Falls, A World Heritage Site|
UNESCO operates with several themes one of which involves the World Heritage Center which identifies sites to be protected all over the world in an effort to promote the maintenance of cultural, historic and/or natural heritage in those places for others to see. Examples are the Pyramids of Giza, Australia's Great Barrier Reef and Peru's Machu Picchu.
In all there are 981 sites that the World Heritage Committee has deemed to have outstanding universal value. Among other criteria, World Heritage Sites must exhibit significant historical value, or represent a masterpiece of creative human genius, or be an outstanding representation of a natural phenomenon. Countries that have signed the World Heritage Convention, pledging to protect and preserve their sites may nominate sites for consideration by the committee. Once a year, the members meet and go over the nominations and either approve or defer selection for further study.
Nothing is more disturbing than to visit places with a history where evidence of historical significance has been wiped out because of uprisings, natural disasters, war, etc. We can only hope that this effort to preserve our history will continue to provide generations to come with our story.
