The Takeaway
Plastic pollution isn't just a waste problem; it's a transportation network. This study shows how floating trash is rewriting the map of global plant life by carrying species to islands they could never reach on their own.
From the abstract
The present study, for the first time globally report, estuarine macroalgal rafting on plastic debris from tropical mangrove-estuarine ecosystem. Samples were collected from tidepools in Sundarban Biosphere Reserve, India, in August 2025. A total 31 individuals belonging to four macroalgal species were detected on commercial polyethylene terephthalate (PET) bottles (n=2). Red alga Caloglossa leprieurii was mostly observed (24 individuals), followed by Catenella caespitosa (3 individuals), Bostry
