The blue face masks were what probably 95% of the people were wearing during the peak of the pandemic and still wearing today. However, they do not break down so last year I buried one in my garden to see what would happen to it a year later. That was last winter and since then I've found several studies that show these masks take 450 years to break down and last as long as diapers and plastic bottles. And if you look at mask pollution going back to 2020 it would equal 7% of the Great Pacific Garbage Patch of plastic that floats in the Pacific Ocean.
