Microplastics are tiny plastic particles measuring less than five millimeters that have permeated almost every environment on Earth.

These pollutants primarily originate from the breakdown of larger plastic debris or are intentionally added to consumer products like exfoliants.

Once they enter the water cycle, they are easily transported through rivers and oceans due to their small size and buoyancy.

Marine organisms often mistake these particles for food, leading to physical blockages and the accumulation of toxic chemicals in their tissues.

Ultimately, this contamination travels up the food chain, posing potential health risks to human populations that rely on seafood.
