The significance of studying the effect of microplastics on marine ecosystems lies in understanding the long-term impacts of plastic pollution. Microplastics can be ingested by marine organisms, leading to bioaccumulation and potential toxicity within the food web. This not only affects marine life but can also pose health risks to humans who consume seafood. Researching microplastics aids in developing effective strategies for pollution management and fosters awareness about plastic use and waste. Addressing this issue is vital for protecting marine biodiversity and ensuring the sustainability of ocean resources.
