Title: "The Impact of Microplastics on Marine Ecosystem Health: A Comprehensive Meta-Analysis"

This study presents a comprehensive meta-analysis of the effects of microplastics on marine ecosystem health. We analyzed data from 150 peer-reviewed studies published between 2010 and 2023, encompassing a wide range of marine species and ecosystems. Our research question focused on quantifying the impact of microplastic pollution on marine biodiversity, food web dynamics, and ecosystem functions. Using a random-effects model, we found a significant negative correlation between microplastic concentration and species diversity (r = -0.72, p < 0.001). Furthermore, we observed disruptions in food web structures, with a 35% decrease in energy transfer efficiency in highly polluted areas. Our findings highlight the urgent need for stricter regulations on plastic production and disposal, as well as the development of more effective cleanup technologies. This research contributes to the growing body of evidence on the detrimental effects of microplastics and provides a quantitative basis for policy decisions aimed at preserving marine ecosystems.
