In short, microplastics are widespread, accumulating in the remotest parts of our planet. There is evidence of their toxic effects at every level of biological organisation, from tiny insects at the bottom of the food chain to apex predators.

Microplastics are pervasive in food and drink and have been detected throughout the human body. Evidence of their harmful effects is emerging.

The scientific evidence is now more than sufficient: collective global action is urgently needed to tackle microplastics – and the problem has never been more pressing.

    So what effect does this have on the health of humans and other organisms? Over the years, scientists have changed the way they measure this.

    They initially used high doses of microplastics in laboratory tests. Now they use a more realistic dose that better represents what we and other creatures are actually exposed to.

    And the nature of microplastics differ. For example, they contain different chemicals and interact differently with liquids or sunlight. And species of organisms, including humans, themselves vary between individuals.

    This complicates scientists’ ability to conclusively link microplastics exposure with effects.

    In regards to humans, progress is being made. In coming years, expect greater clarity about effects on our bodies

    Okay so the title was lying? We DON’T know what microplastics do to us. We expect it to be bad but haven’t found anything conclusive.
