The Effects of Plastic and Microplastic Waste on the Marine Environment and the Ocean

Globally, plastic pollution is acknowledged as a serious human-caused problem for marine and coastal ecosystems. The main sources of these pollutants in the many ways they enter the ocean are land-based and sea-based. Megaplastic, mesoplastic, macroplastic, and microplastic are among the various sizes and kinds of plastic pollutants that are found in ecosystems. The water, sediment, and biota of marine and coastal environments are widely distributed with primary and secondary microplastics. The vast majority of consumer goods in use today are made of plastic. Every year, almost 280 million tons of plastic are manufactured worldwide, most of which wind up in landfills or the ocean. Plastics can be made from primary chemicals, usually coal, oil, or natural gas, or they can be made by converting natural resources. At least 267 species are impacted by plastic and microplastic globally, including 44% of all seabird species, 43% of all marine mammal species, and 86% of all sea turtle species. Through detrimental effects on human health, shipping, and fishing, this new pollutant has an impact on socioeconomic factors. At the international, regional, and national levels, current and enacted laws, policies, rules, and programs are essential to lowering the amount of plastic waste in the world’s oceans. Last but not least, the plastics industry should implement plastic recycling or upgrading programs to assume global responsibility for the end-of-life of their goods. The main objective of this paper is to show the impact of plastic and microplastic waste on the marine environment and oceans, and some ways to solve this problem.
