Why are microplastics everywhere - even inside us? Science Short

From sports shirts and washing machines to sea salt and seafood, tiny pieces of plastic are travelling through our world in ways scientists never expected. In this week’s Squiz Kids Science Short we investigate microplastics — what they are, how plastic breaks down into microscopic fragments, and why researchers are now detecting them in water, food, air and even human tissue. It’s a fascinating look at the invisible journey of plastic around our planet… and inside our bodies.
