Observing the effects of microbes using satellites can give us all sorts of useful information about life on Earth ... and other planets too.
Thanks also to our Patreon patrons / minuteearth and our RU-vid members.
And thanks to researchers from the University of Wisconsin and the University of Nebraska-Lincoln who help generate airborne data used in Professor Jeannine Cavender-Bares' studies.

To learn more, start your googling with these keywords:
Microbe - an organism (such as a bacterium or protozoan) of microscopic or ultramicroscopic size.
Remote sensing - the scanning of the earth , especially by satellite or high-flying aircraft, in order to obtain information about it.
Pathogen - a bacterium, virus, or other microbe that can cause disease.
Chlorophyll - a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
Phytoplankton - photosynthesizing microscopic biotic organisms that inhabit the upper sunlit layer of almost all oceans and bodies of fresh water on Earth.
Cholera - an infectious and often fatal bacterial disease of the small intestine, typically contracted from infected water supplies and causing severe vomiting and diarrhea.
Evaporite - a natural salt or mineral deposit left after the evaporation of a body of water.
Microbially induced sedimentary structures (MISS) - primary sedimentary structures formed by the interaction of microbes with sediment and physical agents of erosion, deposition, and transportation.
