How do you know they are plastic? Interesting! Rotflmao.
Not familar with scale of things, huh? So lets say you get 5 plastic straws in a pack. Lets say in a single town, 100 packs were distribited from 2 health clinica. That is 500 straws a day...
Now....in the same town...there are 20 fast food type establishment with drive through. They each service 100 people in a 2 hour lunch period. That is 2000 straws being introduced in 2 hours.
Scale of things...market.....is just one. Have fun out there
