Millions of tiny bits of plastic floating above our heads

Microplastics aren’t just swirling around our oceans, they’re also floating around in the air and that could be influencing how our climate is changing, according to New Zealand research published today in the journal Nature, The Spinoff reports. But how much of an effect those plastics have is still unclear. “It’s quite uncertain due to a whole number of data gaps in our analysis and the assumptions we had to make,” says environmental physicist Laura Revell. What’s more clear is how bad airborne microplastics can be for human health. They can lead to breathlessness, crackly breathing, developing cancer and more.
