It’s pretty easy - show the effects and the cause and not a visualization of something that you can’t see. Like in the movie Dark Waters where they showed cows dying and birth defects, then the plant that produced PFAS nearby to tie it together.

That water pollution is neon green goo, air pollution is thick black smoke, or radioactive waste is only in drums.

Most of it is invisible and you don’t know about it until it’s too late.
