The Quiet Underground
📋 What it is
Soil is packed with microbes that recycle dead matter and feed plants — the hidden engine of nature.
🗣️ Coach says
A single handful of soil holds billions of microbes. They’re nature’s recycling crew: breaking down dead leaves and creatures into nutrients, and partnering with plant roots to feed them. Without soil microbes, forests and farms would grind to a halt — the underground is quietly running the world above.
🧠 Memory hook
Soil microbes = nature’s recyclers. They rot dead stuff into nutrients + feed plant roots.

😲 Whoa!
One teaspoon of healthy soil can contain more microbes than there are people on Earth — billions of tiny recyclers in a single spoonful.
