Human interaction, water contaminants like microplastics, and disease are also common causes of death. There are about 300 dolphins in Charleston, a number Rust said has stayed relatively stable.
The types of marine pollution can be grouped as pollution from marine debris, plastic pollution, including microplastics, ocean acidification, nutrient pollution, toxins and underwater noise. Plastic pollution in the ocean is a type of marine pollution by plastics , ranging in size from large original material such as bottles and bags, down to ...

They are vulnerable to marine pollution (oil spills, untreated sewage, run-off from agricultural areas, etc.) and subsequent marine bacterial bloom, which causes harm to coastal cetaceans. Toxins from the bacteria in the water can easily wipe out a critically endangered species, like the Atlantic Humpback dolphin.
