A. The proliferation of plastic products since the mid-20th century has brought undeniable convenience to modern life, but it has come at a significant environmental cost. A growing concern is the prevalence of microplastics, tiny plastic particles less than five millimetres in diameter. These particles originate from two primary sources. Primary microplastics are those intentionally manufactured at a small size, such as microbeads found in cosmetic products like facial scrubs and toothpaste, or plastic pellets used in industrial manufacturing. Secondary microplastics, which constitute the majority of oceanic plastic pollution, are formed from the fragmentation and degradation of larger plastic items, such as bottles, bags, and fishing nets, through exposure to sunlight, wind, and wave action. B. In the marine environment, the effects of microplastics are profound and far-reaching. Marine organisms of all sizes, from microscopic zooplankton to large whales, are known to ingest these particles. For smaller creatures at the base of the food web, microplastics can be mistaken for food, leading to internal abrasions, blockages of the digestive tract, and a false sense of satiation. Th…
