All roads lately seem to keep coming back to the Plastic-cyclopedia post I wrote several weeks ago. Especially this Plastic Free July!
If you recall, microfibers were one of the five variations of microplastics. They are the shed that comes off in the washer and dryer from your fleece and polyester-blend clothing. They are essentially the furballs of our clothing that wash down our sinks and make their way to our waterways and ultimately our marine life, easily mistaken as phytoplankton or zooplankton....which then becomes circular (in completely the wrong way) and perhaps wind up in our seafood dinner.
Eco with Em (Australian author and illustrator Emily Ehlers) has posted some dynamic illustrated infographics on microfibers. May her art inspire you to take notes of your own shedding and furballs.
