Marine pollution is defined by the Group of Experts on Scientific Aspects of Marine Pollution (GESAMP) as: “the introduction by man, directly or indirectly, of substances or energy into the marine environment resulting in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities including fishing, impairment of quality for use of sea water, and reduction of amenities”. We understand what the meaning is, but do we know how much of the effect it really does cause? Have you ever imagined a world where one day the water will be overly polluted it would dangerous to drink? …show more content…
One of the top reasons is sewage, in which polluting substances flow through the sewage and goes right into the ocean. The release of chemical nutrients leads to the reduction in oxygen levels, as well as a serious decline in the quality of sea water and that affects the life of plants and animals.
Ship pollution is one of the large sources of ocean pollution with oil spills being the largest effect. Marine animals are generally suffocated from oil spills because crude oil lasts in the water for years and is extremely toxic to marine life. It is also very challenging to clean up the spill, so it is never touched and just remains in the water. Littering is one of the top reasons why marine pollution is so high nowadays. Since plastic debris can’t be decomposed, it remains in the ocean for years which means that animals can mistaken it for food, slowly killing them over a period of time. Turtles, dolphins, fish and crabs are just some of the animal’s that are harmed with the act of littering. The International Convention for the Prevention of Pollution of the Sea by Oil was concluded 30 years ago and was the first attempt taken seriously to cope with the increase of marine pollution. Since then, pollution of the seas by oil, chemicals, nuclear waste has continued to grow and has caused much more serious

Toxic waste such as oil spills can cause long-term effects on marine life which includes cancer, failure in the reproductive system, behavioural change and death. Oxygen levels in the water are constantly decreasing which is caused by the debris not having the ability to decompose and uses the oceans oxygen as a way to degrade. The result of oxygen levels

Starting with the seafood that they eat at this current rate of acidification will dissolve the shells of living organisms within decades (Foy. 1) that contribute to key organisms in the marine ecosystem to most popular seafood that they eat like crab and shrimp. Species that make shells out of calcium carbonate are particularly compromised in acidic waters, where the carbonate ions needed for shell-making are not available. (Leader.…

    Not only does direct contact with oil destroy the coral, but also even with clean up attempts, large traces of oil can still be found. As a result, any habitats damaged by oil do not fully recover, if at all. ("Coral Reefs and Oil Spills"). All of these factors combine to eradicate entire ecosystems (Oceana). Therefore, the immense quantity of oil released from offshore oil drilling poses a large risk to the wildlife and their valuable habitats.…

The algae live on the coral, feeding it with the byproducts it uses, the specific temperature requirement for the chemical process and enzymes is very delicate. The Great Barrier Reef demonstrates the effect of the acidification and ocean heating. The ocean ph is dropping rapidly, reducing its ability to regenerate and house organism, which already endemic only to the reefs. The temperature is hotter than ever with evidence with the Authorities of the Great Barrier Reef stating, "Analysis of coral cores in centuries-old corals suggests that current temperatures are warmer now than over the last three centuries.…

    Humans have been polluting the Earth for many years now and it is showing. People mistakes, like littering are now having an impact on our marine wildlife. Islam and Tanaka reported “that as many as 600,000 plastic containers worldwide were being dumped daily at sea by shipping.” Fish or turtles can swim through these objects and get the plastic stuck around them. This could lead to deformation within the body of the animal. Also, this could even harm the fish and turtles, or even kill them.…

    Much of the plastic accumulates on the ocean 's floor, as well as chemicals like lead and mercury killing the organisms that come into contact with them. Secondly, many fisheries exploit deep sea resources due to the lack of them on land and in shallow waters. Although the climate change may play the biggest factor in years to come. Increased water temperature could devastate this ecosystem so badly due to the adaptations they have acquired to become so accustomed to what it is now, which inevitable will kill them. All these negative impacts could cause the loss of so many organisms and resources, many of which that have yet to be discovered, leaving them to be an opportunity missed or a mystery unsolved forever.…
