Microplastics: From The Oceans to Our Plates & Why You Should Care

Microplastics: From The Oceans to Our Plates & Why You Should Care

Research is growing regarding an invisible environmental threat - microplastics. These tiny plastic particles are pervading our ecosystems, impacting marine life, wildlife, and even human health. Let's learn a little bit more about what microplastics are, where they are found, how they get there, and most importantly, what we can do to help decrease their presence. Understanding the importance of tackling this issue is crucial for the preservation of our planet and its inhabitants.


What are Microplastics?

Microplastics are small plastic particles with a diameter of less than 5 millimeters, barely visible to the naked eye. In fact, some you can't even see without the use of a microscope. They come in various forms, such as microbeads used in personal care products, microfibers from synthetic textiles, and fragments resulting from the breakdown of larger plastic items.

Where are Microplastics Found?

Microplastics have infiltrated almost every corner of the globe. Here are some common places where they are found:

  1. Water Bodies: Rivers, lakes, oceans, and even tap water can contain microplastics due to runoff, industrial discharges, and the breakdown of plastic debris.
  2. Soil and Sediment: Microplastics can accumulate in soil through the application of plastic-based fertilizers and the breakdown of plastic waste in the environment.
  3. Air: Microplastics are so pervasive that they can even be found in the air we breathe, likely due to the fragmentation of plastic litter and fibers from clothing.
  4. Marine Life: Microplastics pose a significant threat to marine organisms. Microplastics can be ingested directly or indirectly through the food chain, leading to adverse effects on marine life and potentially reaching our plates through seafood consumption.


How do Microplastics Get There?

The journey of microplastics into our environment is multifaceted:

  1. Plastic Pollution: Improper disposal of plastic waste, including single-use plastics, contributes to the buildup of microplastics in water bodies and soil.
  2. Washing of Synthetic Fabrics: Washing clothes made of synthetic materials like polyester and nylon releases microfibers into wastewater, which eventually reach water bodies.
  3. Breakdown of Larger Plastics: Over time, larger plastic items, such as bottles and bags, degrade into smaller fragments due to sunlight, waves, and mechanical forces.
  4. Personal Care Products: Microbeads, commonly found in exfoliating scrubs and toothpaste, can wash down drains and enter water bodies.

How Can We Help Decrease Microplastics?

  1. Reduce Single-Use Plastics: Choose reusable alternatives like stainless steel water bottles, fabric shopping bags, and sustainably manufactured food containers to curb the flow of plastic waste into the environment.
  2. Choose Natural and Biodegradable Fabrics: Opt for clothing made from natural fibers like cotton, hemp, or wool, and support sustainable fashion practices.
  3. Avoid Products with Microbeads: Check product labels for "microbead-free" claims and choose environmentally friendly personal care items.
  4. Proper Waste Management: Recycle plastic products correctly and participate in community clean-up efforts to prevent plastic litter from entering water bodies.
  5. Sustainable Manufacturing: Support businesses that are transparent about the processing of their products, use recycled materials, and have thoughtful packaging. Avoid companies that practice “green washing”. 

My eco friendly snack bags use an interior lining that is manufactured using recycled materials including plastic water bottles. The fabric is rated for food safety and is free of PFOAs and PFOS (harmful chemicals that can build up in your body).

Reusables are a great option to eliminate the need for single-use plastics while supporting sustainable practices.

Why Does it Matter?

The consequences of microplastic pollution are far-reaching:

  1. Impact on Marine Life: Microplastics pose a severe threat to marine life. Marine animals, such as fish, turtles, seabirds, and marine mammals, often mistake microplastics for food. This can lead to ingestion and internal injuries, causing blockages in digestive tracts, malnutrition, and even death. Additionally, microplastics can accumulate in the tissues of marine organisms, potentially affecting their reproduction and overall health. As microplastics move up the food chain, they can further impact larger predators, including humans who consume seafood.
  2. Human Health Concerns: The presence of microplastics in the food chain raises concerns about potential health risks to humans. While the direct impact on human health is still being studied, there is growing evidence that microplastics can accumulate in human tissues and organs. The long-term effects of ingesting microplastics are not yet fully understood, but research suggests they may have adverse health consequences, including inflammation, cellular damage, and the potential to carry harmful chemicals into the body.
  3. Ecosystem Disruption: Microplastics can disrupt delicate ecosystems and ecological processes. For example, when microplastics contaminate soil and sediment, they can affect soil health and nutrient cycling, potentially leading to reduced agricultural productivity. 
  4. Environmental Legacy: Microplastics are highly persistent in the environment, taking hundreds of years to degrade fully. Once released into the environment, they become an enduring legacy of our plastic consumption. The accumulation of microplastics in the environment means that even if we stop adding new plastic, the problem will persist for generations to come. Addressing the issue of microplastics now is essential to prevent further buildup and mitigate long-term consequences.
  5. Threat to Biodiversity: The presence of microplastics can lead to a decline in biodiversity. When marine species consume microplastics, it can negatively impact their survival and reproduction rates, leading to a reduction in population size. This ripple effect can affect the entire ecosystem, as each species plays a crucial role in maintaining ecological balance.
  6. Economic Implications: Microplastic pollution also has economic implications. For instance, the presence of microplastics in marine environments can lead to increased costs for the fishing industry. Reduced fish populations due to microplastic ingestion can affect fishing yields and the livelihoods of fishermen and coastal communities.
  7. Sustainable Development Goals (SDGs): Microplastic pollution directly undermines several of the United Nations' Sustainable Development Goals. It hampers efforts to achieve Goal 14: Life Below Water (conserving and sustainably using the oceans) and Goal 15: Life on Land (protecting and restoring terrestrial ecosystems). Additionally, it can also affect Goal 3: Good Health and Well-being, as human health is intricately connected to the health of the environment.

Microplastic pollution is a multifaceted problem that has far-reaching implications for the environment, wildlife, human health, and economic stability. Taking decisive action to reduce microplastics is vital to safeguarding the planet's delicate ecosystems, preserving biodiversity, and securing a sustainable future for all living beings. 

Understanding the sources and consequences of microplastics empowers us to take meaningful action. By making conscious choices, supporting sustainable practices, and advocating for responsible waste management, we can collectively reduce the presence of microplastics in our environment. Let’s unite in preserving the beauty and vitality of our planet for generations to come.
