The World Is Choking on Microplastics

Updated on April 25, 2019

I've spent half a century (yikes) writing for radio and print—mostly print. I hope to be still tapping the keys as I take my last breath.

Far from big cities and dense human habitation, scientists are finding deposits of microplastics. The small fragments are defined as five mm or less; that is about the size of a grain of rice and smaller. These tiny beads are in our oceans, on our land, and part of the food and water that sustains us. And not much is known about how they might affect our health.

Creation of Microplastics

Plastic production is big—very big. About 335 million tonnes of the stuff is turned out every year. It’s estimated that about half of that amount is used just once.

In The Independent, Chelsea Ritschel writes that “Currently, only nine percent of the world’s plastic is recycled - a problem because most plastics are not biodegradable and typically take more than 400 years to degrade.

And it never fully degrades, rather it breaks down into smaller and smaller pieces that are eventually ingested by marine life.” And it's not just marine life; that delicious red snapper you had for dinner contained a side order of microplastics.

The tiny pieces of plastic don’t just come from discarded shopping bags, food containers, and packaging; some is manufactured on purpose. Plastic microbeads are put into such products as cosmetics, toothpaste, and detergents, although some jurisdictions are now banning this technology.

Wind-Borne Pollution

Once discarded, single-use plastics don’t stay where they are dropped. That pop bottle, carelessly chucked out of a car window, might lie in the ditch for decades slowly breaking apart.

Some of it might be carried into rivers and lakes by a gully-washer rainstorm. Other tiny particles might be picked up by the wind and taken far afield. Saharan Desert sand provides a model for how this happens.

In June 2018, dust from the Sahara was seen to be landing in Texas. The National Aeronautics and Space Administration explains: “Normally, hundreds of millions of tons of dust are picked up from the deserts of Africa and blown across the Atlantic Ocean each year. That dust helps build beaches in the Caribbean and fertilizes soils in the Amazon.”

The same dynamic works with microplastics that are picked up in one location and dumped somewhere else.

Wilderness Plastics

The Pyrenees separate Spain and France. There’s a secluded area in the mountains thought to be pristine wilderness in which scientists have found deposits of plastic trash.

A team from universities in Scotland and France estimates that 365 pieces of microplastic settle on every square metre of the area daily. But, the pollutants have been found farther from human habitation than that.

In 2018, Greenpeace mounted an expedition to the Antarctic. Australia’s SBS News reports that microplastics “were detected in nine of 17 water samples it collected on its expedition.”

The fact is there’s no place on Earth that doesn’t have microplastic deposits. These substances are ubiquitous, as Fiona Harvey reports (January 2019) in The Guardian, they have been found “from tap water and seawater to flying insects and are probably even in the air we breathe. Last year, a study found microplastics in human faeces for the first time.”

Effects of Microplastics

Most plastics are made from hydrocarbons; that is coal, oil, and natural gas. From these feedstocks, chains of molecules are created called polymers, and these are formed into plastics.

The “poly” is used to name many plastics such as polypropylene, polythene, and polystyrene.

Polymers on their own are not considered to be toxic, but other chemicals such as chlorine, sulphur, and phosphorus are added to create various plastics. These additives can leach out of the plastics and cause harm.

In 2011, the University of Gothenburg, Sweden reported on a study conducted by Delilah Lithner of the Department of Plant and Environmental Sciences. She tested 83 randomly selected plastic products and found a third of them “released toxic substances, including five out of 13 products intended for children.”

Microplastics also turn out to be hosts for bacteria. In 2018, researchers from the National University of Singapore collected 275 microplastic samples from beaches. Today (Singapore) reported that “Of the more than 400 types of bacteria that the researchers had discovered on microplastics here and then identified through DNA sequencing, about a third are considered toxic …”


Deonie Allen of the EcoLab Research Institute, Toulouse, France, is one of the many people studying microplastics. She says not enough is known about particles that are small enough to be breathed in. “That is a really big unknown,” she says, “and we don’t want it to end up with something like asbestos.”

It seems that humans have blundered into a massive public health experiment without having a clue what the outcome might be.

“Microplastics are being found absolutely everywhere [but] we do not know the dangers they could be posing. It’s no use looking back in 20 years time and saying: ‘If only we’d realised just how bad it was.’ We need to be monitoring our waters now and we need to think, as a country and a world, how we can be reducing our reliance on plastic.”

Christian Dunn, Bangor University, Wales

Bonus Factoids

Polymers occur in nature; cellulose in the cell walls of plants is a polymer.

British inventor Alexander Parkes produced a material he called Parkesine in 1856. It was a celluloid-based material that was a commercial flop. In the United States, John Wesley Hyatt improved on Parkesine and created what is thought to be the first economically viable plastic.

According to The Independent, about 150 million tonnes of waste plastic is already in our oceans and this is added to by an amount “equivalent to a garbage truck full of plastic dumping plastic into the ocean every minute.”

The ultimate symbol of humankind’s inability to handle plastic in an environmentally sound manner is the Great Pacific Garbage Patch. Riding on ocean currents, a vast mass of plastic floats in the waters between Hawaii and California. The garbage covers an area that is twice the size of Texas and three times the area of France.

      As individuals and corporates, the environment could be better. Thanks.

      Informative and helpful. Thanks for sounding the alarm. Each person can participate in necessary action. Hope we do.

      I agreed. Here in Lagos, Nigeria, a school got into partnership with a plastic disposal firm for parents to pick up microplastics at a certain rate in exchange for school fee. At other places, gifts were given so that the plastic wastes are gathered for recycling.

      Sometimes individuals need to take the initiative. We have groups in the UK who voluntarily clear debris from beaches.

      Hello, Liz, I totally agreed with you. I was once concerned about all these for a long time. So I took the initiative to mobilized some guys to help me. But unknown to me, politics was running in the forefront. They told me not to worry until the government wades in.

      Then an incident occurs. Some batch of soldiers were draft into the area to stop an unrest situation among the youths. I ask for the soldiers' permission to burn up the wastes, and they said it is okay, and I go ahead. I am a fisherman and on a fishing expendition there then.

      When the army left the area, refuse continued to heap up and flow into the nearby creek and river at an alarming rate. Marine life is destroyed and no person has fished there again for the past ten years.

      Three days ago, I took a shot of the part of the creek flowing with microplastics. I will later post the same for discussion in the forum. Thank you. Happy Sunday, and happy Eater.

      A combination of all those ideally. We all have a part to play.

      Hi, Liz, I agreed. Whose responsibility can this be? Government, corporate organizations, or individuals? I think there is yet to be a law for this. Thank you.

      We are dealing with an environmental timebomb. This is an informative and helpful article. Sadly it looks like too little action is being taken too late.

      The amount of microplastics is so horrible for our planet. We need to use some things that Marshall Mendoff has developed. For instance, he can make plastic silverware that will degrad in 3 months or whenever we want. He uses plant cellulose and makes so many products that do not harm the environment. Your article sure tells us what a huge problem these microplastics are for our world.

      The real shame is that most of the plastics discarded can be recycled and used over and over almost infinitely. There is no reason the leading nations haven't mandated recycling other than sloth and greed.

      Hello, Rupert, thanks for sharing. This plastic materials canhardly decad for up to 50 years.
