Summary

New research reveals microplastics can reduce plants' photosynthetic ability by 7-12% on average, with variations across terrestrial crops (6-18%), marine plants (2-12%), and freshwater algae (4-14%).

This pollution could cause 4-13.5% yield loss in staple crops over 25 years and decrease seafood production by up to 7% as aquatic ecosystems suffer.

Beyond threatening food security, reduced photosynthesis hampers carbon sequestration efforts critical for climate change.

Researchers estimate that reducing environmental microplastics by just 13% could mitigate photosynthesis loss by 30%.
