Activity 3.3.3 – My Plastic Use
“Throughout human existence water has faced a continuous threat of pollution, and while the threat of pollution has remained constant, the types of pollution have evolved and expanded over time. Currently, freshwater ecosystems across the planet are being threatened by a new form of pollution—microplastic pollution.” (The Environmental Impacts of Microplastics: An Investigation of Microplastic Pollution in North Country Waterbodies by Samantha Haab Kimberly Haab; page 9). Microplastics are tiny plastic particles measuring less than 5 millimeters in diameter. They can be categorized into two main types: primary microplastics, which are deliberately manufactured at small sizes (such as microbeads in cosmetics and industrial abrasives), and secondary microplastics, which result from the breakdown of larger plastic items due to environmental factors like sunlight, heat, and mechanical abrasion. These minuscule plastic fragments are now ubiquitous in the environment and pose a growing concern for both ecosystems and human health.
Microplastics have been detected in virtually every part of the planet, from the deepest oceans to the highest mountains. They are prevalent in marine and freshwater environments, found in sediments, rivers, lakes, and even drinking water. Studies have shown their presence in Arctic ice, agricultural soil, and even the air we breathe. Additionally, microplastics are increasingly found in the food chain, with traces appearing in seafood, salt, honey, and even human blood and organs. Their widespread distribution highlights the difficulty of containing plastic pollution once it enters natural systems.
Microplastics enter the environment through multiple pathways. Primary microplastics are directly released through industrial processes, wastewater from cosmetic products containing microbeads, and synthetic fibers shed from clothing during washing. Secondary microplastics are generated when larger plastic waste items, such as bottles, bags, and fishing nets, degrade over time due to exposure to sunlight, waves, and weathering. Stormwater runoff, industrial discharge, and improper waste disposal all contribute to the dispersion of these pollutants. Additionally, microplastics can be transported by wind and ocean currents over long distances, making their contamination truly global.
Microplastics pose serious threats to both the environment and human health. In aquatic ecosystems, marine organisms, including fish, plankton, and seabirds, mistakenly ingest microplastics, which can cause internal injuries, blockages, and reduced nutritional intake. These particles can also absorb and transport harmful pollutants, such as heavy metals and persistent organic chemicals, which accumulate in the food chain and potentially impact human health.
For humans, microplastic contamination is an emerging concern. Studies have detected microplastics in bottled water, tap water, and even air, raising concerns about ingestion and inhalation. Although the long-term health effects remain uncertain, researchers suspect microplastics could contribute to inflammation, oxidative stress, and other health issues. Moreover, additives used in plastic production, such as phthalates and bisphenol A (BPA), have been linked to endocrine disruption and other toxic effects.
The pervasive nature of microplastics and their potential risks highlight the urgent need for global action to address plastic pollution. Strategies such as reducing plastic production, improving waste management systems, promoting biodegradable alternatives, and strengthening regulations on plastic use can help mitigate the spread of microplastics. Increased public awareness and scientific research are also crucial in tackling this growing environmental challenge. As microplastics continue to infiltrate ecosystems and human bodies, addressing this issue is essential for safeguarding environmental health and future generations.
The photo collage I made has a couple of items I use mostly daily. All of them items have some form of plastic in them or are made from plastic. With almost every day use of the items shown above, they are bound to leave some sort of micro plastics behind as a trace of their use. Over time from using and washing the dishes, utensils, and other plastic items, micro plastics will be prevalent in my day to day life.
