Here's one from island nation of Mauritius and how an environmental group has rallied together the community and the visitor industry to protect their marine resources.
"Reef conservation is a local marine environmental engine. We started up in 2004 and our project were based around education and sensitization of the Mauritian public and school children," said Kathy Young of the Reef Conservation Mauritius. "Our projects kept evolving and with our program, we were approached to set up a marine resource center."
They began looking at ways to protect the coral and shallow reefs. The group set up voluntary marine conservation areas where they are working with the communities on what are the viable areas that need protection.
They also got the hotels involved and began teaching hotel staff what was found in the lagoon so they could share that with their guests.
And they put in this unique snorkeling trail. It is 250 meters long. As you swim along you can read descriptions of what types of fish and coral can be found in the area as well as the importance of protecting them.
The crew of the Hokulea is expected to leave Mauritius this weekend as they head to Madagascar and Africa.
