The Dangers of Microplastics
Share
Microplastics, tiny plastic particles less than 5 millimetres in size, have become a pervasive pollutant in our environment, posing significant dangers to both wildlife and human health. These particles originate from larger plastic debris that breaks down over time, as well as from products like synthetic clothing fibres, cosmetics, and industrial processes. Once in the environment, microplastics are nearly impossible to remove and are readily consumed by marine life, from plankton to fish and even larger mammals. This ingestion can lead to physical blockages, injury, and toxic effects, as microplastics often carry harmful chemicals like pesticides, heavy metals, and endocrine disruptors. As these particles move up the food chain, they not only impact wildlife but also pose potential risks to human health through the consumption of contaminated seafood and water. Recent studies have even found microplastics in human blood, lungs, and placental tissue, raising concerns about their long-term effects on our bodies. Beyond ingestion, microplastics contribute to broader environmental problems, such as soil degradation and the disruption of natural ecosystems. The ubiquity and persistence of microplastics underscore the urgent need for global action to reduce plastic pollution, promote sustainable alternatives, and protect both environmental and human health from this invisible yet pervasive threat.
