In Norway, people generally don't litter and we have a good culture where many or most people generally try to pick up and dispose of garbage if they see it. Wireweed here is basically sea garbage that can reproduce. If people only knew about Japanese wireweeds and how it affects ecosystems, I'm sure they'd wanna help keep their favorite swimming spots wireweed free.
