Ugh.

• fluids should be around two 3rds of what you consume every day by weight. Reducing microplastics in there by 80% is a huge improvement, not at all comparable to your dieting allegory
• for the same reason, the microplastics we breathe in are unfortunate, hopefully some day eradicated, but negligible compared to what we consume
• it's not my fault your country still allows lead based solder and you don't know what a tea pot is. Hot tip: You can boil your water every day in it.
• Again, people can care about 2 things at once. Just because I don't have any idea how to deal with the great pacific garbage patch doesn't mean I might as well eat the plastic wrapper with my food inside it.
