There are more microorganisms in a teaspoon of soil than people on Earth.
✓ TRUE FACT
Soil is incredibly dense with life: ~1 gram (about ¼ teaspoon) can contain ~1 billion bacterial cells, so a teaspoon can reach several billions depending on soil type. If you include other microbes (and not just bacteria), some soils can plausibly exceed the human population in a spoonful. (UC Davis)
