💡 Analysis & Explanation
Nature of Microbeads ▼
Microbeads are tiny manufactured solid plastic particles (usually less than 5mm in diameter) heavily used in personal care products like exfoliating face washes, toothpaste, and cosmetics.
Environmental Hazard ▼
Because of their minuscule size, they effortlessly bypass water filtration and sewage treatment plants, draining directly into rivers and oceans. Once in the marine ecosystem, they are ingested by aquatic life (such as plankton and fish), introducing toxic plastics directly into the food web and causing fatal blockages in marine animals.
Conclusion ▼
Their devastating impact on marine ecosystems is the primary global concern, making option A correct.
