There’s currently a massive problem brewing in our oceans caused by the teeny tiniest of all suspects — microplastics.
What are microplastics?
Microplastics are tiny plastic particles less than 5 millimeters in length — the diameter of a pencil-top eraser — that are incredibly invasive.
The fossil fuel–derived materials that make up synthetic plastic don’t occur within nature, so no naturally occurring organism can break them down. The plastic will only break down into smaller pieces.
When large plastic pieces break down in nature, these fragments are secondary microplastics.
Why do we care about microplastics?
These tiny pollutants are proving to be a massive issue.
A team of scientists found 24.4 trillion pieces of microplastics — though the actual amount is likely to be much higher — just in our oceans, forming a plastic soup.
The small size of microplastics allows them to invade the environment. To date, microplastics are in the stomachs of various wildlife, the air, soil, tap water, oceans, bottled water, beer, and the fish we eat.
And because of this small size, microplastics can be nearly impossible to clean up. It takes far more effort and resources to remove microplastics from the environment than to remove larger pieces of plastic.
Experts are still uncertain if microplastics are a danger to human or animal health — and if they are, we don’t know how or to what degree these plastic particles can harm us.
Albert Koelmans, an environmental scientist at Wageningen University, said, “if you ask me about risks, I am not that frightened today, but I am a bit concerned about the future if we do nothing.”
Ways to help fight microplastics
There are ways you can help reduce the production of microplastics and prevent them from entering our environment.
One of the easiest ways to tackle microplastics is through your clothes by opting for more natural, organic fiber clothes when you can, or even washing synthetic fabrics less frequently.
Another way to help is by reducing the amount of plastic you buy or use, such as investing in a reusable water bottle.
Operations like Mr. Trash Wheel and scientific discoveries, such as magnetic liquids used to collect small plastic particles, are also aiding in the fight against microplastics.While individuals do their part to fight microplastics, companies and industries must do the same by using plastic alternatives and operating or producing under a circular model.
