Bacteria, viruses, but also fungus spores, algae, pollen, and even insects: microorganisms are constantly drifting through the sky.

Biodiversity, health, climate - scientists are only now discovering just how much this discreet airborne "plankton" affects our lives and the entire ecosystem on Earth. But despite its many virtues, this magic matter is now under threat from human activity.
