It could backfire though because people now understand that microplastic = bad so all we need to say is "You know those pesky microplactics? Yup. Well, basically tyre!".
You're so right! When something is almost 80% of a thing, it's more or less that thing now. It's that thing, plus some other stuff but the focus has to be on the thing that is almost 80% of the issue. If we reduce car tyre derived microplastics by one quarter it would be the equivalent of completely eliminating ALL other sources of microplastics. The issue needs reframing badly!
