Microplastics, tiny plastic particles less than 5 millimeters in diameter, are a growing concern. These particles, originating from various sources like personal care products and the breakdown of larger plastics, contaminate environments worldwide, including oceans, soil, and even the air. Their impact on ecosystems is significant, affecting marine life and potentially impacting human health through ingestion, inhalation, and chemical exposure. While the full extent of health risks is still under investigation, concerns include inflammation, potential disruption of gut microbiota, and interactions with other toxins. Addressing this issue requires a multifaceted approach involving policy changes, technological innovation, and increased public awareness.
