Do you like fog? Fog looks like a white cloud on the ground. It is often cool and wet. Now, scientists have found something amazing. Fog is full of life! Inside the tiny water drops, there are very small living things. They are called microbes. You cannot see them with your eyes because they are so small. These microbes do an important job. They eat bad chemicals in the air. These chemicals make the air dirty and can make people sick. By eating them, the microbes help clean the air we breathe. A scientist named Thi Thuong Thuong Cao studied fog in a large field. She saw that the microbes grow and live happily there. Fog is not just gray and quiet. It is a busy home for millions of tiny helpers. Next time you see fog, remember the little microbes working hard to help our planet!
