Thesis Overview

The research project titled "Investigating the impact of microplastics on marine ecosystems" aims to address the pressing issue of microplastic pollution in marine environments and its detrimental effects on marine ecosystems. Microplastics, which are small plastic particles less than 5mm in size, have become a major environmental concern due to their widespread presence in oceans and coastal areas, posing threats to marine life and ecosystems. The research will delve into the sources, distribution, and types of microplastics found in marine environments, including their physical and chemical properties. By reviewing existing literature on microplastic pollution, the project aims to provide a comprehensive understanding of the scope and scale of this environmental issue. Furthermore, the research will investigate the potential impacts of microplastics on marine organisms, such as fish, seabirds, and marine mammals, as well as on marine habitats like coral reefs and seagrass beds. By examining the mechanisms by which microplastics interact with marine organisms and ecosystems, the study seeks to elucidate the ecological consequences of this pollution. The methodology of the research will involve field surveys, laboratory experiments, and data analysis to quantify the abundance of microplastics in marine samples, assess their toxicity to marine organisms, and evaluate the ecological risks they pose to marine ecosystems. Through these research methods, the project aims to generate empirical data that can inform policy and management strategies for mitigating microplastic pollution in marine environments. Overall, this research project seeks to contribute to the growing body of knowledge on microplastic pollution in marine ecosystems and highlight the urgent need for effective solutions to address this environmental challenge. By investigating the impacts of microplastics on marine life and habitats, the study aims to raise awareness about the importance of preserving marine ecosystems and promoting sustainable practices to protect the health and integrity of our oceans.
