There is “a growing concern” over microplastics pollution in farm soils, Kate S. Petersen reported for Environmental Health News this week. Although we have long since known about the effects of microplastics in the ocean, this article showed that “most microplastics are actually accumulating on land, including agricultural areas.”
Why This Matters: Microplastics, as Petersen noted, change the properties of soils, both in a physical and biological sense. As Mary Beth Kirkham, a plant physiologist and distinguished professor of agronomy noted that in her experiments, “The particulate plastic appeared to clog the soil pores, prevent aeration of the soil, and cause…the roots to die.” Although we don’t know the “full impact of microplastics contamination in agricultural soils,” burgeoning research suggests that microplastics can pass through plant— and, when ingested by people potentially impacting our immune systems.
Banning the Beads: There are some places that are moving forward in limiting microplastics and microbeads. In particular, the EU said next year they would “seek a ban following a proposal from EU agency the European Chemicals Agency (ECHA) to prevent the addition of microplastics to certain products sold in Europe,” as Euractiv reported.
While ECHA claimed that was to make sure the restriction “could be enforced,” the European Environmental Bureau noted that this “gives manufacturers a perverse incentive to switch production from micro to nano plastic, which may be more harmful to human and animal health because it can more easily get inside and harm living cells.”
We’ve also seen from the Obama-era Microbead-Free Waters Act in the United States, that bans which focus on eliminating plastic microbeads from a single industry are too narrow and allow other manufacturers to keep using them in myriad other consumer products.
By Amy Lupica, ODP Daily Editor Today, the World Wildlife Fund (WWF) released its 2021 Plowprint Report, which tracks the amount of grasslands lost to plow-up each year. This year’s study found that plow-up across the Great Plains has only continued to accelerate, releasing exorbitant amounts of carbon into the atmosphere. The report concludes that […]
By Ashira Morris, ODP Staff Writer With global temperatures rising and rainfall patterns changing, global agriculture is shifting too — with big changes projected. Places like Siberia and northern Canada that have been too frigid for farming in centuries past are expected to become cropland by the end of the century. But it’s not a […]
By Amy Lupica, ODP Staff Writer The National Park Service has closed down a large swathe of Alaska’s Denali National Park after excessive permafrost thawing caused landslide activity near the park’s only access road. The access road is now closed, blocking entry to about half of the park. Park officials say that although there have been landslides in […]
