There was a nice article yesterday in The Cavalier Daily about Hales Parcells, a college student who turned her love of mermaids and her passion for ocean conservation into a program of teaching school kids about preservation of the Chesapeake Bay while wearing her mermaid tail.
It is another great example of merging passions and social betterment programs.
Many mermaid performers are very active in ocean conservation, and it is a recurring theme also in mermaid art.
The growing enthusiasm and interest in mermaids is a great springboard for raising awareness about ocean conservation.
