Support local mooring programs by adopting a mooring site. Be aware of your Poisson in the water. Do not stand, kneel or hold on to corals or marine rocks. These actions may destroy the coral or other living organisms that have extremely slow growth rates. Always know what is around your fins.
Fins do the most damage.
Avoid collecting souvenirs of marine animals. The removal of marine animals from the environment can reduce the biodiversity in heavily visited dive areas. Corals and shells are slowly produce by animals and can take a long time to be replaced naturally. They also provide habitat and shelter for other animals. Become educated about the areas you dive.
