You Live on a
Planet of Microbes
More than 90% of the
Earths biomass is microbial.
Microbes can be found everywhere.
Deep below the sea floor, high up in
the clouds, and even inside us.
Microbes are our best friends. They fix
carbon dioxide and methane - green -
house gases that would otherwise
reach the atmosphere and speed up
global warming. Microbes even
degrade the toxic waste we produce.
