When future geologists want to identify in their digs and surveys the point at which the Anthropocene began, all they need do is locate the plastic.
“A sediment core taken off the coast of Southern California shows the first appearance of micro-plastic in its sedimentary depth layers around 1950s, with a subsequent doubling about every fifteen years thereafter,” writes Roland Geyer, a professor at UC Santa Barbara’s Bren School of Environmental Science & Management. That we continue to saturate the environment — and ultimately ourselves — with plastics is a grim reminder that even after half a century of Earth Days, we still have a long way to go.
“The long-term consequences of such pervasive and near-permanent plastic pollution are unclear at this point, but there are many reasons to expect significant adverse ecological and human health effect,” he continues.
Geyer’s written reflections on the state of the world’s relationship to plastic is part of an open-source, online book titled “Earth 2020: An Insider’s Guide to a Rapidly Changing Planet” (Open Book Publishers, 2020). Edited by University of British Columbia professor Philippe Tortell, the book is a compilation of 26 essays by global experts in diverse environmental fields around the international phenomenon that is Earth Day, an annual celebration and acknowledgement of our ties to nature.
“The book project, namely to explore how Earth has changed in the 50 years since the first Earth Day, was instantly appealing to me, especially since it is aimed at a wide, non-technical audience,” Geyer said. His chapter, “Earth and Plastic,” examines the rise of petrochemical products, particularly plastic.
“Using plastic as an environmental indicator provides a unique perspective on humankind’s impact on the natural environment, and Earth more broadly,” said Geyer, whose research emphasis — industrial ecology — causes him to look at the impacts of things the rest of us tend to overlook, like plastic packaging, waste and single-use items.
The news is sobering. On the first Earth Day, when plastics as a common material was about 20 years old, global production was about 37 megatons. By 2017, annual production had increased elevenfold, and cumulative production had reached 9.2 gigatons — or as Geyer illustrates, “900,000 Eiffel Towers, or 88 million blue whales, or 1.2 billion elephants.” The material we are trained to ignore is now ubiquitous, showing up in our water, in animals, even at the bottom of the Mariana Trench, the deepest part of the ocean.
Furthermore, measures designed to mitigate our use of plastic, but not actually aim at reducing our use, such as recycling, incineration and landfill can accomplish only so much: A mere 9% of all plastic ever made has been recycled, Geyer estimates, and landfill, incineration and even biomass-based materials each have environmental costs and limited effects. To truly fulfill our Earth Day obligations, he noted, we would have to substantially reduce the amount of plastic we produce and use.
“Our relationship with plastic makes it very clear why, after 50 years of Earth Day, we are still so far away from living sustainably,” Geyer said.
Got a solution? It is impossible to live in this world without plastic.
Wow, K1, that’s news! Better notify all the historians and paleontologists!
The Earth and plastic, courtesy of George Carlin:
The planet will be here for a long, long, LONG time after we’re gone and it will heal itself, it will cleanse itself cause that’s what it does. It’s a self-correcting system. The air and the water will recover, the earth will be renewed, and if it’s true that plastic is not degradable, well, the planet will simply incorporate plastic into a new paradigm: The Earth plus plastic. The Earth doesn’t share our prejudice towards plastic. Plastic came out of the Earth! The Earth probably sees plastic as just another one of its children. Could be the only reason the Earth allowed us to be spawned from it in the first place: it wanted plastic for itself, didn’t know how to make it, needed us. Could be the answer to our age-old philosophical question: “Why are we here?” PLASTIC!!! A****OLES!!!
Maybe plastic kills Covid-19. Someone needs to start lining up research grants to figure this out. Go plastic!
