Looking at https://ourworldindata.org/plastic-pollution#how-does-plasti... I see a lot of reasons to believe plastic can be harmful, but nothing about the scale of the harm. Is plastic pollution about as bad greenhouse gas pollution? 10x as bad? 0.1x as bad? Decent estimates here would be really important for figuring out what we should focus on.

(My completely uninformed guess is that it's ~0.01x as bad, but if anyone has something more informed that would be very helpful!)

Refine your thinking..."bad" is not a research outcome. Define your question more specifically and it will be much easier to quantify the difference. What are you interested in -- climate change, effect on ocean life, effect on human health, etc.?
