Abstract

Water covers about 71% of the Earth’s surface and is a basic need for all the oceanic fauna and flora. According to the Ocean Pollutants Guide, 2018, marine life is constantly being harmed and there is an abundance of plastic pollution still found on the shorelines. Along with that, oceanic dead zones have expanded four times since the 20th century. If harm to the oceans continues, then there is a chance that every species of animals existing in the marine environment will be endangered. All of this is due to anthropogenic activities such as sewage entry into the oceans, oil spills and plastic pollution which form the top three oceanic pollutants, destroying the marine ecosystems. These pollutants negatively affect fish, bivalves’ crustaceans, birds and mammals which are directly associated with water. This leads to reduced life expectancy, and cancer formation in said organisms. Unless stopped, these pollutants will be the cause of death of marine fauna.  It is recommended to examine the oceanic water quality, prevent ocean pollution and clean the polluted water bodies, by all necessary means.
