On average, you consume between 74,000 and 121,000 microscopic pieces of plastic every year. Probably much more. Where does it come from?
According to new research from Penn State Behrend chemist Sherri Mason, 60 percent of the microplastics in our freshwater comes from laundry lint making its way from your washing machine through wastewater treatment plants. From American Scientist
As we clean our clothing, sheets, and towels, tiny threads—commonly called microfibers—break off and wash away. To better understand how microbeads and microfibers—collectively making up microplastics—move through the Great Lakes and other freshwater systems, we wanted to understand whether they are removed at wastewater treatment plants.
After collecting and analyzing 90 samples taken from 17 different facilities across the United States, we confirmed that microplastics travel through wastewater treatment plants. On average, each wastewater treatment facility was releasing more than four million pieces of microplastic into U.S. waterways every day: 60 percent fibers, 34 percent beads, and 6 percent films and foams. With 15,000 such facilities in continual operation around the United States, billions of microplastic particles are finding a pathway through our wastewater from our homes to the fresh water we rely on.

Antti Lipponen of the Finnish Meteorological Institute created this troubling but unsurprising chart of almost 140 years of temperature anomalies by country. The data used was from the NASA GISS, Land Ocean Temperature Index. You can probably guess what will happen.
In ten years, scientists hope to have mapped the entire ocean floor in high resolution. This week, the Nippon Foundation-GEBCO Seabed 2030 Project announced that they’ve completed 20 percent of the map. A full mapping to “modern standards” is useful for conservation and also to support scientific understanding of ocean systems, weather, tsunami wave propagation, […]
Twenty-five experts have issued a warning about the potentially cataclysmic consequences of the rapidly shrinking insect population, reports The Guardian. In a two-part article for Biological Conservation, the scientists wrote: “The current [insect] extinction crisis is deeply worrisome. Yet, what we know is only the tip of the iceberg.We know enough to act immediately. Solutions […]
If the last 50 years of education have taught us nothing else, it’s that it often requires different tactics to best reach different learners. To pick up a foreign language, some students take best to the old-school high school language lab method, using heavy repetition, verb conjugation and grammar emphasis to embed a new language. […]
For those who want a career in video games, there’s no reason to sit around and wait. EA and Rockstar Games probably aren’t going to seek you out and knock on your door with a job opportunity. But if you’re an indie developer with a good idea and some passion, you can create a really […]
Nobody is happy about the current state of our COVID-ravaged education system. With a new school year fast approaching, plans for teaching students still in flux, and political in-fighting driving more fear and confusion about whether or not to re-open campuses, teachers and parents are concerned. Meanwhile, most kids are just fine with spending less […]
