It's not all doom and gloom, my friend! Certain photocatalysis reactions can reduce most(~90%), if not all micro-plastics in wastewater with the obvious downsides being that it requires a constant power source and takes significantly longer than conventional treatment.
One could also leverage the use of microorganisms like Chlorella or crude plant extracts during pretreatment but that is probably beyond the scope of what you're thinking.
I regularly employ the use of biodiversity data like SEINet to crossref with herbarium specimens. Honorable mention to the North American Ethnobotany Database for pulling up bibliographic info on plant-human interactions. There's also a tool to lookup collection site IDs for cacti and succulents here: BCSS Field No. Lookup. These aren't necessarily in the realm of plant care but I believe they could make a nice additon to the sidebar. Cheers!
Okay. I guess caring about finding practical solutions to our problems is a waste of brain cells. Have fun in your echo chamber of misery!
