What’s for dinner? Lego sushi, credit card burgers, or a well-done piece of PVC pipe?
Well, these examples may sound extreme, but can easily represent over time the cumulative amount of microscopic pieces of plastic we consume each day.
A 2019 study conducted by WWF International said that people could be ingesting the equivalent of a credit card of plastic a week, not only in plastic-infused drinking water but also via food like shellfish, which tends to be eaten whole so the plastic in their digestive systems is also consumed.
Reuters used the findings of the study to illustrate what this amount of plastic actually looks like over various periods of time.
We ingest the weight of a 4×2 Lego brick in plastic in a month and in a year, the amount of plastic in a fireman’s helmet.
This may not sound like a lot, but it can add up. At this rate of consumption, in a decade, we could be eating 2.5 kg (5.5 lb) in plastic, the equivalent of over two sizable pieces of plastic pipe.
And over a lifetime, we consume about 20 kg (44 lb) of microplastic.
Plastic production has spiked in the last 50 years with the widespread use of inexpensive disposable products. Plastic is not biodegradable, it only breaks down into smaller pieces, ultimately ending up everywhere, cluttering beaches and choking marine wildlife. It also enters our food chain.
Standing on the shoreline of a wildlife-protected saltmarsh in southern England, Malcolm Hudson, a professor of environmental science at the University of Southampton, shows Reuters small, bead-like plastic pellets that permeate the marsh.
Hudson says that most research has been done on these microplastics, but there are increasing amounts of even smaller particles called nanoplastics in the environment that are far more difficult to detect, which we are likely ingesting as well.
“It could pass into our blood or lymphatic system and end up in our organs,” said Hudson.
“Those plastic particles are little time bombs waiting to break down small enough to be absorbed by wildlife or by people and then potentially have harmful consequences.”
