Global action is urgently needed to tackle microplastic – and the problem has never been more pressing.

Scientists reviewed 7,000 studies on microplastics. Their alarming conclusion puts humanity on notice

Microplastics have been identified in the water we drink, the air we breathe and the food we eat – including seafood, table salt, honey, sugar, beer and tea. Sometimes the contamination occurs in the environment. Other times it’s the result of food processing, packaging and handling. More data is needed on microplastics in human foods such as land-animal products, cereals, grains, fruits, vegetables, beverages, spices, and oils and fats.

As equipment has advanced, scientists have identified smaller particles. They’ve found microplastics in our lungs, livers, kidneys, blood and reproductive organs. Microplastics have crossed protective barriers into our brains and hearts. While we eliminate some microplastics through urine, faeces and our lungs, many persist in our bodies for a long time.
