–What are the types of marine pollution?

Marine pollution can take many forms, such as:

Garbage

  • Plastics thrown into the sea can stay there for many years and harm marine life. A huge number of marine animals die every year from either ingesting or becoming entangled in plastic trash.
  • Garbage can also threaten ships and raise costs when it becomes trapped on propellers and in seawater intakes.

Sewage

  • Sewage contains chemicals that alter the marine environment, causing some marine life to die and other marine life to flourish. This throws off the natural balance of marine ecosystems.
  • Sewage can also deprive marine environments of oxygen, killing off entire populations in affected areas.

  • When released into the oceans, chemicals used in the shipping industry (sometimes referred to as chemical runoff) can cause harm to marine life as well as to maritime workers.
  • Oil poisons marine life, and oil slicks keep sunlight from penetrating the ocean’s water, killing plants and damaging the entire marine ecosystem.
  • Noise from a ship’s sonar can have devastating effects on marine animals like whales and dolphins that use sound to communicate with one another.
