Ballast water pollution

The letting out of the ballast water from ships is a major cause of pollution. Since the ballast water contains microbes and micro-organisms in addition to vegetation and other sea animals, the pollution aspect is mainly caused to the local species and marine life.

Oil pollution

Oil pollution is the main reason for the increased level of marine pollution. Bilge oil mixing with oceanic water causes serious marine pollution. Faulty engine systems and improper repair work are two areas through which oil could leak and mix with the oceanic water. Collisions and accidents are also a reason for oil pollution. Since oil is heavier than water, it does not degrade quickly leading to problems to marine creatures and plants that are forced to ingest such polluted water.
