At least nine thousand divers dive in Bunaken national marine park every year. With the number of divers coming to see the coral reefs there tend to increase every year, efforts to protect the underwater environment are needed due to frequent damages or disturbances caused by tourist divers and their guides, and boat manuevers in shallow waters.
In general, tourism activities might create damages which can be categorised as follows:
- boat collision with reefs
- pulling or disturbance of propellers on shallow seagrass
- diver damage
- pollution from sewage,
- pollution from solid wastes
- pollution from sediments during the homestay construction
- increasing number of fishing activites in supplyng the tourists.
On the other hand, due to its closer location to Manado city, the Bunaken national marine park is facing more damages from:
- urban coastal development which is not related to tourism
- river flooding
- pollution from the city
- poison fishing for ornamental aquarium fish business
- and etc.
- practice body control and buoyancy to keep safe distance from life corals and marine life.
- never stand or walk on living corals. In case of strong current, look for large rock.
- do not dispose of rubbish into the ocean or onto the ground.
- When finding drifted plastic bags or other waste materials that cover the corals, please take them up as your contribution in cleaning up these coral reefs.
