Microplastics are tiny plastic particles, typically less than five millimeters in size, that result from the breakdown of larger plastic items or are manufactured for use in products like cosmetics and cleaning supplies. These particles are pervasive in the environment, found in oceans, rivers, soil, and even in the air. Microplastics pose a significant threat to wildlife, as animals can ingest them, leading to physical harm or chemical contamination. They also enter the human food chain through seafood consumption. Despite their small size, microplastics are difficult to remove from the environment due to their durability and widespread presence. Their impact on ecosystems and human health is still being studied, but scientists are increasingly concerned about the long-term effects of this pollution. Reducing plastic usage is a key strategy to mitigate microplastic contamination.
