Which is the most important pollutant of the marine environment in Nigeria?

The most important pollutant of the marine environment in Nigeria is oil. Nigeria is a major oil-producing country, and oil spills from oil exploration, transportation, and processing activities have caused significant damage to the marine environment. These oil spills release toxic chemicals and pollutants into the water, affecting marine life, ecosystems, and the livelihoods of people who depend on the sea for their sustenance. In addition to oil spills, other pollutants such as sewage, insecticides, and inorganic fertilizers can also contribute to marine pollution, but the impact of oil spills is considered to be the most significant in Nigeria.
