We are completely screwed. Since plastic is around for decades, the exposition of disintergating plastic into micro- and nano plastic particles is also.
Almost everything you have, use, eat, drink etc. contains plastic, which is disintergrating due to mechanical abrasion or chemical reaction.
Examples: food - packed in plastic containers; beverages - filled into plastic containers, tin cans have an inner layer of plastic; paint - made of plastic; wood glue - made of plastic, the mattress you sleep on - made of foam, which is plastic; your clothes - contain plastic; your non stick frying pan - coated in plastic.
