Ocean Pollution by Microplastics: Sources, Impacts and Global Challenges

Summary

This review paper pulls together existing research on how tiny plastic fragments called microplastics are polluting our oceans—from sources like broken-down packaging and synthetic clothing fibers to their effects on marine life. Since fish and shellfish can absorb these microplastics, and we eat seafood, this pollution may end up on our plates, raising questions about long-term health effects that scientists are still working to fully understand. The bottom line: reducing plastic waste isn't just about protecting sea turtles—it's likely connected to what ends up in our own food and bodies.
