Microplastics and the 'Terrible Debris of Progress' |
Microplastics, those miniscule particles smaller than 5 millimeters which plastics physically break down into, have now infiltrated every part of the planet – from the highest point of the Himalayas; to the deepest depths of the sea; to the snow of Antarctica. They penetrate all layers of ocean and are often mistaken for zooplankton and consumed by fish. Consequently, people of coastal countries and islands who are highly dependent on the sea for food are consuming microplastic contaminated fish.
Scientists have recently detected microplastics in human blood, breast milk, heart arteries, lungs, testicles, brains and placentas, foreboding serious human health consequences.
A 2024 study found that 99 percent of seafood samples in stores and West Coast fishing boats were contaminated with microplastics. Plastics, made from oil and gas and toxic chemicals and manufactured largely in poor, communities of color in Texas and Louisiana, are a major source of greenhouse emissions and air pollution. Plastic recycling is a master myth, given 5-6 percent are actually recycled in the U.S. as of 2021, despite a century of existence.
When I first learned that plastic flakes filled my lightweight winter jacket, I thought “great”—recycling plastic rather than throwing it away. But I have since learned what Judith Enck, author of The Problem with Plastics, and other critics prescribe: the best thing we can do is reduce the use of plastic in our lives to bring our planet back from this runaway pollution. Yes, we can re-use as much as certain plastic allows, which is not back to itself like wood, paper, metal, and glass. It is “down-cycled” at best, like the filling in my jacket, before disposed in a landfill, or incinerated, or dumped unconscionably in a poor, developing country.
Invented a century ago, plastic is now ubiquitous, having increased from about 2 million tons annually in 1950 to one half billion tons a year today, and projected to triple by 2060. Plastics are derived from fossil fuels, which are converted into chemical components such as ethylene and propylene—the building blocks for plastics. They were first manufactured as nylon and PVC, then boosted by use in WWII and subsequently Increased by the middle-class love affair with single-use products, such as straws, coffee cups, and water bottles. Agricultural fields are polluted with plastic through the use of plastic-contaminated sewage sludge. irrigation water, and plastic films to suppress weeds. These then........
