Sedimentation due to deforestation
Near-shore coral reef systems are experiencing increased sediment supply due to conversion of forests to other land uses. Counteracting increased sediment loads requires an understanding of the relationship between forest cover and sediment supply. All of this eroded sediment seeps into the river and is carried along. An increase in sediment load has many adverse impacts: it can smother fish eggs, diminishing fish populations and hurting the ecosystem as well as the fishing industry, it can damage the infrastructure of a country by destroying bridges and dams which may hurt the coral reefs economy, and it can increase flood rates and sizes by raising the river bed.

Dynamite fishing

Blast fishing or dynamite fishing is the practice of using explosives to stun or kill schools of fish for easy collection. This often illegal practice can be extremely destructive to the surrounding ecosystem, as the explosion often destroys the underlying habitat (such as coral reefs) that supports the fish. Underwater shock waves produced by the explosion stun the fish and cause their swim bladders to rupture. This rupturing causes an abrupt loss of buoyancy; a small number of fish float to the surface, but most sink to the sea floor. The explosions indiscriminately kill large numbers of fish and other marine organisms in the vicinity and can damage or destroy the physical environment, including extensive damage to coral reefs
