The provided source offers a comprehensive analysis of microplastic pollution, examining its pervasive presence from environmental origins to human health impacts. It details how these tiny plastic particles originate from both intentionally manufactured products and the fragmentation of larger plastics, subsequently spreading through terrestrial, freshwater, and marine ecosystems. The text highlights the direct biological harm to wildlife through physical injury and cellular disruption, alongside the chemical threat from leached additives and adsorbed environmental pollutants. Crucially, the source confirms human exposure and internal accumulation of microplastics, linking them to chronic inflammation and emerging risks for diseases such as cardiovascular issues, and underscoring the urgent need for a global, multi-faceted response including policy, research, and sustainable solutions.
