It is a well-known fact that nearly 70% of the earth is filled with water in the form of different kinds of water bodies such as oceans, lakes and rivers etc. All these water bodies, especially oceans and seas, form an indispensable part of our existence as it has key roles to play in our everyday life. This factor of indispensability has not only helped us tremendously, but has also resulted in the exploitation of the oceanic resources without any second thoughts.
The careless human intervention has badly affected the oceanic ecosystem, threatening the existence of several other species on earth, including human beings. Accidents such as BP oil spill and Samarco dam collapse are the striking instances to see how badly the human activities can destroy the rich ecosystem of water bodies.
Causes of Ocean Pollution
Dumping sewage in the ocean has always been considered the cheapest and the easiest way of disposing of wastes. The billions of tons of litter end up in the ocean each year reportedly bring 250 million tons of trash into the sea every year. However, reports also suggest that littering makes the aquatic life in the oceans and seas worse in these days.
1. Ocean Dumping
Among all sorts of activities that pollute the ocean, dumping of garbage and other waste materials stands first in the list. Dumping involves depositing all the waste materials from factories and industries, tankers and ships and sewerage waste materials into the oceans and seas. Some of the materials emitted by the industrial wastes and sewage wastes contain materials like mercury, cryolite and DDT. Certain industrial wastage also includes radioactive materials. Even small amounts of these substances tend to have negative effects. The scale and the magnitude of the ocean dumping are not just vast but are so huge, that our entire civilisation could be wiped out with the intensity of careless dumping. The discharge of ballast water also causes the problem by way of ocean waste. Ballast water tends to proliferate and transfer organisms that debilitate the growth of naturally occurring fishes in a particular oceanic area.
2. Land Runoff
According to researchers, many pollutants, almost eighty percent pollution, are released into the marine environment far upstream from coastlines. The non-point pollution, which is a result of land runoff brings many wastage materials such as the debris of cars and boats into the sea every day. Moreover, rivers during floods pick up harmful contaminants including fertilizers, petroleum, and pesticides, among others. Studies have suggested that the presence of fertilizers in the ocean will result in the sudden explosions of marine algae, which can disrupt ocean ecosystems, and also the creation of dead zones in the waters.
3. Oil Spills
Spilling of oil from tankers and offshore rigs in the oceanic area is also another example of sea pollution. Several of such oil spills from tanker ships after accidents, including Deepwater Horizon, Gulf War oil spill and Atlantic Empress, have shown us the extent of the damages the spills can do to the ecosystems. Spilling of oil can happen inadvertently where small doses of oil are leaked into the oceans by the tanker ships or in a massive scale where gallons and gallons of oil are leaked into the water surface of the ocean after the collision of vessels or capsizing. The pollution through oil spills can have serious consequences for society, both economically and environmentally. Importantly, the main victims of oil spills are birds and mammals. The Gulf of Mexico oil spill has caused problems to birds among the other marine creatures whose wings had gotten covered by the slick, causing them to die a slow and painful death.
4. Littering
Beaches covered with plastic wastes are not a rare scene in these days. Besides the large chunk of industrial wastes, the dumping of plastic is another biggest source of pollution as it slowly leads to adverse effects. Materials like plastic are non-degradable which means they will not be absorbed and recycled. When oceanic creatures and even birds consume plastic inadvertently, they choke on it which causes a steady decline in their population. Activists say who suffer from the plastic debris are dolphins, sharks, turtles, crabs, and sea birds, among others. The Pacific Ocean Garbage Patch is a very good example of plastic being hazardous and Islands like Henderson have transformed from the beautiful lands to Plastic Junkyards.

As we are becoming more and more than an industrial day by day we are constantly harming and polluting our mother nature.
The oceans are also becoming polluted due to our garbage disposal in the ocean water.
Marine ecosystem is one of the most important ecosystem in the world because it is the largest ecosystem in the world.
That's why we have stop the excessive disposal of the garbages in the ocean water in order to prevent the polluted marine ecosystem.
