We know that certain levels of plastic can kill organisms, but we're not necessarily seeing it play out in a way that's endangering whole species. We don't know at which concentrations those effects are to happen for a lot of species. And i think that we should do more rigorous science and more rigorous analysis on how really the interaction between oceans plastic and organisms impacts ego systems. Because it is really much more complicated than what you would see by looking at a wale.
