While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
The MV Wakashio oil spill occurred after the Japanese -controlled bulk carrier Wakashio ran aground on a coral reef on 25 July 2020 at around 16:00 UTC. The ship began to leak fuel oil in the following weeks, and broke apart in mid August. Although much of the oil on board Wakashio was pumped out before she broke in half, an estimated 1,000 ...
The noise produced by ships can travel long distances, and marine species who may rely on sound for their orientation, communication, and feeding, can be harmed by this sound pollution. [11] [12] The Convention on the Conservation of Migratory Species has identified ocean noise as a potential threat to marine life. [13]
