Thanks to the University of Minnesota for sponsoring this video! http://twin-cities.umn.edu/

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 https://www.patreon.com/MinuteEarth and our YouTube 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.
