Coastal exploitation

Changes in the coastal environment and the alteration of the shoreline, as well as changes of the characteristics of the seabed through dredging and the build-up of offshore structures, also has negative effects on the aquatic ecosystems. These negative effects include increased turbidity, which might disturb the biological production, and increased sedimentation, which can decrease the supply of oxygen and cause hypoxia. Further, the noise from boats and water scooters might have disturbing effects on the local environment.
