I do applaud the article for using visual aids to show the 'size' of the problem.
I do feel that there should have been mention of microplastic coming from tires and brakes and that it should be mentioned that not all 'plastic' is the same. (in chemical composition, chemical activity and by that the impact on nature/human health)
I learned about the microplastic issue (coming from tyres) from my college professor. he argued that it's a major problem and yet most people don't know about. That's because stakeholders (global leaders) know there's nothing much that can be done to avoid this issue so they withhold this info from the general public.
