The word “microplastics” has been a buzzword in the recent news for the past couple of years – but the exact reason why microplastics are a problem seems to be evasive.
Current research shows that microplastics have made their way just about everywhere on earth, but what does that mean for you?
This blog is going to discuss exactly what microplastics are, how they impact us, and what we can do collectively to help prevent any further damage from being done.

Why Microplastics Are A Problem: What Are Microplastics?
Microplastics are small pieces of plastic less than five millimeters in length that can be potentially harmful to our environment and our own bodies. There are two different kinds of microplastics one of which has been banned from being made in 2015 which are plastic pellets used in personal items.
“Primary microplastics, such as microbeads used in personal care products or the pellets used in plastics manufacturing, are intentionally manufactured small. Secondary microplastics are the consequence of one of the plastic’s most valued assets: its durability. They begin as discarded products that are broken down in the oceans by sunlight and wave action. Over time, the fragments become smaller and smaller. They will presumably survive for centuries (National Geographic).”
One of the main issues with microplastics is their longevity. Plastic is not able to decompose and will presumably just remain on the earth permanently. Because of this the amount of plastic floating around in the oceans is now starting to affect the food chain and is getting ingested by humans without us even realizing it.
Scientists are now finding microplastics are not only in the oceans but in the air as well swirling around as small dust particulates. In the year 2015, an estimated 8.8 million tons of garbage was deposited into the ocean. This number has only gone up since then and impacts the food chain, and the water cycle as well with microplastics being found in rain and water (National Geographic).
Microplastics are now everywhere – and there doesn’t seem to be a way to control the damage that has already been done, but how much do they really impact our day-to-day?
Why Microplastics Are A Problem: How They Impact Humans
As the research on microplastics continues, the findings about just how large of an issue these plastics are continues to grow.
Ingesting plastic, no matter the scale is presumably not a good thing for anyone to do. However, a recent study by the Medical University of Vienna said that heavy plastic users are potentially consuming a credit card’s worth of microplastics a week.
This is an issue – let’s dive into the certain areas of life that microplastics are drastically impacting and if there is any way to reverse the damage that has already been done.
The biggest threat that microplastics pose to humans is the toxicological effects that ingesting plastic has. Toxicology is the science of understanding how certain chemicals and substances can harm the human body – so eating tiny microplastics on a daily basis will eventually have a negative outcome on humans.
One of the more concerning toxicological threats to humans from microplastics is the oxidative stress created as your body has an incredibly difficult time filtering out microplastics you ingest, which can trigger inflammation and other health issues.
“MP’s can induce oxidative stress by producing oxidizing substances adsorbing to their surface, as well as reactive oxygen radicals created by the host during the inflammation (Frontiers).”
This is from research that was published in 2014. It’s safe to assume this problem has only worsened since then. The good news is, there are simple steps you can take to avoid microplastics, which we discuss further down in the article.
Immune System Dysfunction
Consuming microplastics can also affect your body’s ability to fight diseases. Plastics in general are fairly toxic products – having them inside of you will weaken your body’s immune response and can increase the risk of disease.
“Environmental exposure to MPs, on the other hand, was enough to impair immune systems in biologically vulnerable individuals, resulting in autoimmune disorders or immunosuppression (Frontiers).”
The research is not entirely sound on just what kind of immune response your body will eventually have but there is enough evidence to support that inhaling microplastics in the environment will definitely have an impact on our immune systems.
Why Microplastics Are A Problem: What Can We Do?
Microplastics pose a serious threat, so what can we do?
Small changes in your daily life dedicated to avoiding plastic will be all the defense you need against microplastics in your own life. Make sure to:
- Never heat food in plastic containers
- Avoid plastic straws
- Use a non-plastic, reusable water bottle
- Use non-plastic utensils & cooking equipment
These suggestions are small in comparison to the potential damage of microplastics, so consider if you have the ability to make these changes in your life!
Why Microplastics Are A Problem: Final Thoughts
While microplastics pose a real threat to all life on earth, there isn’t much you can do on a day-to-day basis to stop the spread aside from limiting your use of plastic and spreading the word, so don’t stress over it.
Eat nutritious, organic food, cook them in non-plastic cooking equipment, and drink out of non-plastic cups to seriously reduce your risk of microplastics in your life.
