Humans are blanketing the Earth with plastic

A Billion More Tons of Plastic Could Blanket Earth by 2040, Wired, 26 July 20, Even with immediate action, 710 million metric tons of plastic will enter the environment in the next two decades, scientists show. Welcome to Plastic Planet. IMAGINE YOUR FAVORITE stretch of coastline—whitesand beaches, rocky tide pools, the cliffs of Dover, what have you. Now transport yourself ahead two decades, after plastic production and waste have continued to skyrocket. Humanity is now unloading 29 million metric tons of bottles, bags, and microplastics (little bits smaller than 5 millimeters) into the oceans annually. That means for every meter of your favorite coastline, 50 kilograms—that’s 110 pounds—of plastic is entering the sea every year.“Now imagine that’s happening for every meter of coastline around the world,” says Richard Bailey, who studies environmental systems at Oxford University. “That’s the amount we’re looking at—it’s a colossal amount.”

Over the past few years, scientists have been exposing the hazards of microplastics—or ground-up particles that easily blow around the world and work their way into plants and animals. But all the while, macro-plastics like bottles have been accumulating in the environment, shedding microplastics as they degrade. Writing today in the journal Science, Bailey and his colleagues are publishing the alarming findings of their comprehensive review of the cycle of all this plastic. If we as a species don’t collectively take action, they warn, 1.3 billion metric tons of plastic will flow into the sea and tumble across the land between the years 2016 and 2040. Even with immediate and drastic action, that figure could be 710 million metric tons—460 million of them on land and 250 million in the water. Making matters worse, throughout much of the world people burn the plastic they can’t easily recycle, to the tune of perhaps 133 million metric tons of waste by 2040. That spews dangerous toxins and CO2 (plastic is made of oil, after all), further warming the planet.

To model the plastic waste ecosystem, the researchers created eight “geographic archetypes,” instead of picking apart the dynamics of how individual countries handle trash. “We didn’t want it to become a blame game,” says the study’s co-lead author, Winnie Lau, senior manager of the Pew Charitable Trusts’ project on ocean plastic pollution. “What we wanted to do was to understand the problem and how it came about, rather than pointing out specific countries.”…………

Without drastic and immediate measures, the fight against plastic pollution will follow the same path as the fight against climate change: We’ve waited far too long to stop CO2 from accumulating in the atmosphere, and we’re in danger of waiting far too long to turn off the plastic spigot. “What this paper makes clear is, really, any future scenario for a healthy planet is going to require that this kind of year-over-year growth in plastic production has got to stop,” says Leonard. “It began in 1950, and it continues to accelerate. And there’s really no viable solution that doesn’t result in bending that curve.” https://www.wired.com/story/billion-more-tons-of-plastic-could-blanket-earth/
