- Coral reefs show signs of stress
- Overfishing – Fishing of juvenile fishes for the live reef fish trade increases the impacts of high fishing effort as well as commercial fishing which lacks a proper management plan
- Destructive fishing – Fish bombing and cyanide fishing are still carried out which affect coral reefs, mangroves and coastal waters.
- Abandoned fishing nets which entangle marine animals
- Fish of high market value, sea cucumber and giant clam were not recorded during the expedition, also another indicator of overfishing of these commercially valuable species.
- Unsustainable coastal land use - Increasing number of projects and inappropriate development plans could lead to pollution of coastal waters, unnecessary destruction of mangrove forests and nursery habitats.
- Hunting and collection - Illegal turtle eggs collection have driven many turtle species to the brink of extinction. For example, in March 2014, the 60 sea turtle carcasses discovered may be part of an international syndicate to smuggle turtles.
It is estimated that conservation and ecotourism expansion would bring in a value of RM343 million, exceeding extractive industries of limestone and silica sand mining at only RM100 million. Therefore, economically it makes sense to lean more towards sustainable tourism and biodiversity conservation.
