As the New York Times wrote, a new study has given more insight into just how pervasive microplastics are in the environment. In addition to being one of the ocean’s greatest pollution threats,
They’re in the air we breathe, traveling on the wind and drifting down from the skies.
More than 1,000 tons of tiny fragments rain down each year on national parks and wilderness areas in the American West alone, equivalent to between 123 million and 300 million plastic bottles worth.
Humans and animals are inhaling and digesting these particles and there’s very little research about what effect they have on human and environmental health.
Why This Matters: This new study shows that even the most isolated areas in the United States, microplastics are ever-present after being transported there by wind and rain. Microplastics are known to be prevalent in the ocean but, as Scientific American explained, their movement through the air is particularly troubling because of the risk of humans breathing them in, a possible health issue that has been little studied so far.
For all of us humans that enjoy the outdoors, that clean, pristine air may not be as pure as we think. Plastic pollution is pervasive, as we’re still learning about its extent.
The Results: As the Times explained, the study researchers concluded that the particles deposited in wet weather were likely to have originated from relatively near by, with the plastic bits swept into the air by storms from urban centers, and then falling again with the rain and snow.
The smaller, lighter particles, they suggested, had, in contrast, been carried extremely long distances on currents high in the atmosphere and had become part of the cycles of global dust transport.
The dry deposits constituted more than 75 percent of the plastic that was tested.
The Response: The Washington Post reported that the National Park Service, for its part, recognized the potential hazards that come with so much microplastics raining down within its protected areas.
“The NPS is concerned about the deposition of microplastics in parks and wilderness areas. The recent study further contributes to the large body of evidence that microplastics are everywhere, including remote and high elevation areas,” said Kristi Morris, a physical scientist in the air resources division of the National Park Service.
The most progressive corporate commitments this week involve nature-based mitigation and pushing sustainability out into their supply chains. Walmart pledged to do some big things, including achieving zero emissions by 2040 without carbon offsets, committing to protect and restore at least 50 million acres of land and one million square miles of ocean by 2030, and promising zero waste in the US, Canada, and Japan by 2025.
Why This Matters: Nature-based solutions have until now been seen as greenwashing. But these new commitments go much farther.
by Natasha Lasky, ODP Contributing Writer A 1000-foot stretch highway in Oroville, CA was recently repaved with recycled plastic and asphalt—the first time a state department has paved a road with 100% recycled materials. This durable recycled material can combat potholes, last two to three times longer than asphalt roads, and reuse about 150,000 single-use […]
Why This Matters: The report is another loudly ringing alarm bell that our current path is unsustainable — and we need to make a huge shift away from “business as usual” across a range of human activities.
