Cross-Examination of Human Activities on Marine Pollution

Cross-Examination of Human Activities on Marine Pollution

The majority of the world’s marine pollution problem today is a result of human actions. The huge seas, which account for around 71% of the Earth’s surface, play an essential role in our ecosystem by providing us with food, moderating our climate, and housing a wide variety of organisms. However, a dramatic increase in marine pollution has resulted from increased anthropogenic activity, endangering the wellbeing of marine species and ecosystems.

The majority of marine pollution comes from land and sea based human activities. Everything from manufacturing and urbanisation to agriculture and fishing is included in this category. Plastics, heavy metals, oil spills, fertilisers, and other substances are all introduced to the marine ecosystem through these activities.

The contamination of the oceans is mostly attributable to industrialization and urbanisation. Heavy metals, chemicals, and radioactive waste are only some of the dangerous items introduced to rivers and oceans when industries dump their wastewater without treatment or with insufficient treatment. Similarly, trash, gasoline, and other toxins from roadways and other urban areas all too often make their way into the ocean via urban runoff.

Marine contamination is also exacerbated by agriculture. Nutrient contamination occurs when agricultural chemicals like fertilisers and insecticides are carried into rivers and finally the ocean. This causes eutrophication, which kills marine life by reducing oxygen levels in the ocean.

Shipping, fishing, and offshore drilling are just some of the maritime activities that add to pollution levels. Ships and offshore oil rigs are a major contributor to pollution, particularly oil spills that have devastating effects on marine life. Both fish supplies and marine ecosystems suffer from overfishing and other damaging fishing practises.

Human activities have a significant and far-reaching effect on marine pollution. It not only endangers marine animals’ existence but also throws marine ecosystems out of whack. To reduce the impact of human activities on marine pollution, it is critical to establish stronger rules on industrial discharges, promote sustainable agriculture practises, and enforce responsible fishing and shipping practises. Educating the general population on the value of marine ecosystems and the hazards of pollution is also crucial for protecting our seas.
