A global review has found that cigarette butts account for roughly 12% of litter in aquatic environments, making them one of the largest single sources of marine and freshwater pollution. The findings highlight the scale of plastic contamination from tobacco filters, which contain cellulose acetate and can release toxic chemicals as they break down in water.

New research suggests that even if flows of plastic into the oceans were halted by 2050, microplastics would continue accumulating in marine environments. Plastics already in the sea are expected to keep fragmenting into smaller particles for decades, meaning cleanup efforts alone cannot undo the damage. Researchers say the findings underline the need for faster action to cut plastic production and waste before contamination becomes effectively irreversible.

A Wired report describes how plastic waste settling on coral reefs can melt onto coral tissue, causing damage to reefs already stressed by warming seas. The story highlights a little-known mechanism by which ocean plastic harms marine ecosystems. Readers are sharing the report as a striking example of how plastic pollution compounds existing threats to ocean life.
