The Age Of Plastic — Study Examines The Ubiquity Of Plastic Pollution/Debris In The Modern World

Plastics are everywhere. It’s gotten to the point where pretty much anywhere you go, anything you do, you’re life is notably influenced by plastic — micro plastic is in the soil you’re standing on, the water you drink, and the food you eat. And, it’ll still be there long after your gone.

So what effect is all of this plastic having on the wider environment? What does it mean for the future of the world, and the life that’ll be around in that future?

A new study from an international team of researchers has examined that subject — and found that plastics will have a profound effect on the world, and can more or less function as a boundary marker for the “Anthropocene” (age of notable human influence on the earth’s surface) epoch. A veritable “Age of Plastic”.

Jan Zalasiewicz, Professor of Palaeobiology from the University of Leicester’s Department of Geology stated: “Plastics were more or less unknown to our grandparents, when they were children. But now, they are indispensible to our lives. They’re everywhere — wrapping our food, being containers for our water and milk, providing cartons for eggs and yoghourt and chocolate, keeping our medicines sterile. They now make up most of the clothes that we wear, too.

“Plastics are also pretty well everywhere on Earth, from mountain tops to the deep ocean floor — and can be fossilized into the far future. We now make almost a billion tons of the stuff every 3 years. If all the plastic made in the last few decades was clingfilm, there would be enough to put a layer around the whole Earth. With current trends of production, there will be the equivalent of several more such layers by mid-century.”

The study press release provides more:

The study suggests that plastics have such a long-lasting impact on the planet’s geology because they are inert and hard to degrade. As a result, when plastics litter the landscape they become a part of the soil, often ending up in the sea and being consumed by and killing plankton, fish and seabirds. Plastics can travel thousands of miles, caught up in the ‘great oceanic garbage patches’, or eventually being washed up on distant beaches. Plastics can eventually sink to the sea floor, to become a part of the strata of the future.

The rise of plastics since the mid-20th century, both as a material element of modern life and as a growing environmental pollutant, has been widely described. Their distribution in both the terrestrial and marine realms suggests that they are a key geological indicator of the Anthropocene, as a distinctive stratal component.

Professor Zalasiewicz continued: “Plastics will continue to be input into the sedimentary cycle over coming millennia as temporary stores — landfill sites — are eroded. Plastics already enable fine time resolution within Anthropocene deposits via the development of their different types and via the artefacts, known as ‘technofossils’, they are moulded into, and many of these may have long-term preservation potential when buried in strata.

“Once buried, being so hard-wearing, plastics have a good chance to be fossilized — and leave a signal of the ultimate convenience material for many million years into the future. The age of plastic may really last for ages.”

Colin Waters from the British Geological Survey, a co-author in the study, commented: “We have become accustomed to living amongst plastic refuse, but it is the ‘unseen’ contribution of plastic microbeads from cosmetics and toothpaste or the artificial fibres washed from our clothes that are increasingly accumulating on sea and lake beds and perhaps have the greatest potential for leaving a lasting legacy in the geological record.”
