Googling, "what are microplastics?". By now, you'll likely have heard that there are microplastics in both the ocean and in humans, too. But how? Why? And since when?
campaigner explains, microplastics are loosely defined as plastic particles that are smaller than 5mm.
, there are "approximately 51 trillion microscopic pieces of plastic [in the ocean], weighing 269,000 tons - about the same as 1345 adult blue whales or 500 times the number of stars in our galaxy."

What are microplastics? Your guide
What's the definition of a microplastic?
As above - tiny, minuscule beads of plastic that can be found in our ocean, food, and even bodies. As Prabhakar explains, there are two different types.
1. Primary microplastics
Primary microplastics are the not-so-obvious sources of microplastic pollution.
"They are called primary microplastics because they are intended to be manufactured at microplastic size," Prabhakar continues. "Often, they're intentionally added to products such as cosmetics, personal care products, detergents, cleaning products, paints."
2. Secondary microplastics
Secondary microplastics are likely the ones that first come to mind when you think of microplastics - the tiny plastic particles. As the name suggests, they're simply bigger plastics broken down into tiny pieces.
explains, they're the "
Shockingly, they're usually found in the ocean and the air. "That's what makes these small particles so insidious - they're literally everywhere and unavoidable," explains Piper.
So, what are the side effects of microplastics?
Aka, should we worry about microplastics? "Absolutely," Piper tells us. "Plastic proliferation is one of the most challenging and harmful issues to people, animals, and the planet," she explains.
They've even found microplastics and still in-tact plastic bags in the deepest known part of the world, the Mariana Trench, which is 37,000 feet deep.
Are there microplastics in the ocean?
website reveals. Prabhakar adds that microplastics are damaging to marine life because marine animals often mistake them for food.
. While this is heartbreaking for the fish who feed on the plastic, it's also damaging for humans who eat the fish.
"They are passed along the marine food chain, and since humans are ultimately at the top of this food chain, we also eat these plastic particles," shares Prabhakar.
On top of that, plastic is very persistent, and once microplastics enter the marine environment, they're near impossible to remove, he continues. With 12 million tonnes of plastic poured into the ocean every year, it's no surprise microplastics have made their way into the human body.
Are there micrplastics in the soil?
.
Fay explains that even organic farming sometimes uses plastic instead of herbicides to suppress weeds, which can cause plastic remnants to remain in fields.
12.5 million tonnes of plastic is used in agricultural production annually - a stat which the Sustainable Soil Alliance is using to encourage the government to put industry measures in place (microplastics in the soil can be damaging to both planetary and human health).
"Microplastics in soils can enter the food chain through plant root systems and animal grazing - which may, in turn, have disruptive impacts on human endocrine systems," explains Fay. "These microplastics can also end up in our waterways through soil runoff."
Are there microplastics in humans?
Finally - yep, you guessed it - microplastics are in humans now, too. One recent study found that 80% of humans have microplastics in their body in some capacity.
which shows that microplastics were found in almost 80 per cent of the sample of people tested," shares Prabhakar.
So, how? In Prabhakar's eyes, it's no surprise as humans have unintentionally infiltrated every corner of the planet and used it to our own advantage. The microplastics are an unwanted byproduct.
, shared with us.
Bottom line: microplastics have been found in many products, including seafood, water, fruit, and vegetables - and in both indoor and outdoor air, too. We eat, drink and breathe microplastics every day - so much so, plastics have even been found in human placentas and blood.
So, are microplastics harmful?
The question on everyone's lips. As Piper explains, plastic is everywhere and it's becoming a part of our physiology as we consume and breathe it in - so is it damaging?
compounds, while others can absorb unwanted chemicals including heavy metals, polychlorinated biphenyls (PCB's), and pesticides that they then transit into our bodies," she continues. These have the potential to cause serious health issues down the line, but the research is limited as it's a new phenomenon.
Unfortunately, that is not the end of it. As microplastic is small enough to enter cells or tissues, they could cause inflammation, allergic response and even cell death. But bottom line? We simply don't know yet. "The fact is, we're so mired in plastics that we don't yet even know the full longitudinal impact of such exposure," Piper goes on.
Prabhakar agrees, adding that it's likely that microplastics can cause inflammation, DNA damage, and cellular damage, among others. But there are still many uncertainties - like how many microplastics are entering our bodies daily, and to what extent these accumulate in our bodies.
How to avoid microplastics: 10 expert tips
1. Wash your clothes less often
Simple. Plus, when you do put them in the washing machine, make sure to wash them at a lower temperature, so they shed fewer microplastics.
2. Get a guppy bag
Alternatively, get a guppy bag or something similar to catch microplastics in your clothing (think polyester and other synthetics) from entering water systems when you do laundry.

3. Watch out for plastic in your beauty

4. Aim for non-plastic
Try to use non-plastic reusable products at home to avoid exposure to potentially harmful chemicals used in plastic products.
5. Track your plastic footprint
, which aims to help you reduce the amount of plastic you use.
6. Buy natural ingredients
Try to opt for items made from natural materials like cotton, linen, or hemp in clothing and furnishings, and plastic-free when shopping.

7. Eat less seafood
Another way to avoid microplastic consumption? Try and reduce your consumption of seafood. Much of ocean-bound plastic comes from plastic fishing nets, and shellfish have been shown to retain a significant amount of microplastics.
guide is full of handy transition tips.
8. Reduce your packaging
Another top tip: opt for items with no packaging or non-plastic packaging whenever possible, like shampoo bars, stainless steel safety razors, bamboo toothbrushes, and natural tooth tabs.
9. Reduce nanoplastics
Did you know? Regular vacuuming, dusting, and air purifying can help with the proliferation of microplastics in the air in your home.
10. Reuse your bottles and cups
With less than a third of all plastic in the UK recycled, one of the simplest things you can do is use reusable water bottles and coffee cups. Carrying a KeepCup often means you get a discount on teas and coffees, too.
