Other Lists of Wonders of the World


Numerous other authors and organizations have composed lists of the wonders of the world. Travel writer Howard Hillman published two books on the subject, one with 10 man-made wonders, and one with 10 natural wonders.[21][22] British biographer, science writer, and novelist Ronald W. Clark is another who has published a list of man-made and natural wonders, in his book Wonders of the World. Rather than having only seven wonders of the world to match the number of days in a week, Clark's list includes 52 wonders, one for each week of the year.[23]


Seven Wonders of the Underwater World


The Seven Underwater Wonders of the World was a list drawn up by CEDAM International, an American-based non-profit group for divers, dedicated to ocean preservation and research.



In 1989 CEDAM brought together a panel of marine scientists, including Dr. Eugenie Clark, to pick underwater areas which they considered to be worthy of protection. The results were announced at The National Aquarium in Washington DC by actor Lloyd Bridges, star of TV's Sea Hunt:[19][20]
