Coastal development can negatively impact the ecosystem of coastal land resulting in pollution and changes that negatively impact the organisms living in the ecosystem. Coastal development can cause chronic sedimentation, sewage effluent, industrial discharge, changes waterflow and run off which can harmfully affect coral growth rates and metabolic activities as well as directly kill corals. They may also damage them indirectly by placing objects into the paths of water flow resulting in changes in the saltiness of water that negatively impacts living organisms present in the area. Along the coast, beaches and dunes are constantly moving with winds and waves, coastal banks are eroding, and large amounts of sand are shifted during big storms. They can be unattractive.
