I am busy and don't have time to research all of the ways corporations have poisoned us.
What are some good rules on how to avoid microplastics?
Eat local foods? Avoid processed foods? Walk/bike? Use dry soaps? Don't use any take away containers? Avoid walking near busy roads? Use cotton/wool for all clothing?
Short answer: very simple
Avoid plastic
You buy bottled water?
That has Microplastics.
You buy or store food in plastic?
Microplastics..
Use plastic straws?
Welp, Microplastics
Etc...
Basically it's difficult to avoid it since we use plastic almost everywhere daily, but not impossible.
Microplastics have also been found in our drinking water. So maybe stop drinking water altogether.
I can confirm that if you stop drinking water, in 72 hours or so you won't have to worry about microplastics.
Car tires and brake pads produce micro plastics in our water system. It's probably impossible on an individual basis to completely avoid them.
