The Invisible Life in the Air

The air around us, previously thought to be empty space, is actually filled with a vast array of microbial life, including pollen, spores, bacteria, and viruses. Studies have revealed staggering quantities: for instance, a single white mulberry tree can produce nearly 486 billion grains of pollen in just one spring season. Additionally, researchers have estimated that around a trillion trillion bacteria are released into the atmosphere annually. This suggests that with every breath, individuals are inhaling thousands of living organisms, highlighting the complexity and richness of our aerobiome.
