Microplastic Pollution: Threats and Impacts on Global Marine Ecosystems

Abstract

This study investigates the scope of global marine microplastic pollution and its implications on marine ecosystems and human health. We first delve into how plastic enters the ocean, with an emphasis on the accumulation of plastic along coastlines, particularly the formation and impact of the Great Pacific Garbage Patch (GPGP). Through a concentration map of marine microplastics across five continents, the global distribution of microplastic pollution is revealed. Furthermore, the effects of microplastics on marine wildlife are explored, as well as their potential entry into the human food chain, posing potential public health risks. The results of our research underscore the serious threats of microplastic pollution to global marine ecosystems and human health, emphasizing the need for more scientific research and policy measures to address this challenge.
