How Microplastics Infiltrate our Everyday Life

By MacKenzie Hand '25

Imagine a world in which poisons are everywhere, yet invisible to the human eye. Microplastics are incredibly tiny plastic particles that are less than 5 millimeters in size. These particles have become a ubiquitous presence in the environment, and are found in oceans, lakes, rivers, and the air. While the impact of plastic particles on the environment is severe, but the extent of their impact plagues human health as well. Microplastics infiltrate our daily lives, posing health threats to both mankind and nature.

Microplastics are produced by a variety of sources, including the breakdown of larger plastic items, such as water bottles and bags. Additionally, microbeads, which are tiny plastic beads found in personal care products, simultaneously contribute to the presence of microplastics in the environment. Products that contain microbeads include facial products, makeup, toothpastes, and many others, so it’s important to be mindful when shopping for personal hygiene. In terms of human clothing, synthetic fibers and textiles are also a major source of microplastics. Brands that yield plastics from their clothing typically fall under the category of fast fashion. Because each of these sources are products of human consumption, it is important to reduce the intake of single-use plastics, non-reputable hygiene products, and fast fashion, in order to eliminate micro-plastic ingestion down the road.

Humans and animals can ingest microplastics under infinite circumstances. Microplastics are present in food, as plastics can break down into tiny particles that can be consumed by marine life. As a result, the seafood industry is infected with these nefarious particles. Additionally, micro-plastics often show up in drinking water, for water treatment plants cannot always remove these particles from filtered water. Furthermore, micro-plastics are inhaled through the air, as they are found in dust and pollution. While microplastics surround us in all areas of existence, their threats towards our health are increasing rapidly. 

The health risks associated with the ingestion of microplastics cast a dark shadow on the future of the Earth. Studies have suggested that micro-plastics may cause inflammation, oxidative stress, and cellular damage in humans and animals. Additionally, micro-plastics may act as a carrier for deadly chemicals and pollutants, which could increase their toxicity. Micro-plastics have been found to accumulate in various tissues of the body as well, including the liver and lungs. The presence of plastic in these vital organs could potentially lead to chronic health problems in the future. While we understand the firsthand effects our actions have on the living population of the world, the need to reduce plastic consumption becomes increasingly crucial.

Sourced by the human plastic intake, microplastics have infiltrated both the environment, and our bodies. Next time you consider purchasing a plastic bag, a water bottle from the school store, fast-fashion clothing, or personal hygiene products, research and reflect on the potential impact on your planet and your organs.
