This claim is uncertain. We could find no credible scientific source to back up it up. The percentage of land- and sea-based plastic inputs into the ocean has not yet been calculated on a global level and therefore remains unknown. Scientific studies show that the ratio of land versus ocean-based plastics can differ strongly depending…
You can read this frequently, but this claim is probably false. It misquotes the results of research published in 2017. In that study, scientists estimated how much plastic enters the sea from rivers around the world. Ten of these river systems carried most of the plastic. But plastic also reaches the sea through other ways,…
This claim is highly speculative, and probably false. We do not know how much plastic is currently in the ocean. There is no scientific estimate for how much plastic will be in the ocean by 2050. It is also unclear how much fish will inhabit the ocean by 2050.
