The first and most common cause is wastewater. Wastewater flows through drains that go directly to oceans or rivers. This causes the ocean to have poor water quality, which can affect the plants and animals that live in the ocean. The world contains many industrial and agricultural places, which causes more waste to be put directly into the oceans, resulting in ocean pollution. But the discharge is not rubbish and sewage, it is toxic liquids and can be very dangerous for marine life. Approximately 14,000 oil spills occur per year, due to storms, accidents, etc. This is a huge part of ocean pollution. Oil can last for years in the ocean and can be really toxic to animals, choking marine life to death once the oil traps them. The oil is also extremely difficult to remove from water, which is why it lasts for years. Oil extraction can also be a major cause of ocean pollution. Ocean mines extract gold, silver, copper and other minerals. This can cause damage to lower ocean levels and increase the region's toxicity. This method can also contribute to the cause of leaks, sometimes oil spills occur during drilling. The last and final cause of ocean pollution is waste. Just like oil spills, this can account for a large portion of the pollution. We talk about littering when an object is blown away by the wind and ends up in the ocean, also due to the poor decisions of humans in throwing garbage into the ocean. Most waste is made up of plastic debris, plastic can be really harmful to animals if they mistake it for food or if it gets stuck
