Curious about Microbiology?
The vast majority of life is too small to see with the naked eye. The unseen microbial world accounts for most of the Earth’s biomass. Most of the cells in and on our own bodies are not our own—they are microbes. Microbes are crucial players in global cycles, removing as much greenhouse gas from the atmosphere as all plant life on Earth.
Beyond that, cellular microbes—bacteria, archaea, and fungi—are greatly outnumbered by viruses. The viruses in the oceans alone are estimated to weigh as much as 75-million blue whales and, if strung together, could crisscross our galaxy 100 times (Suttle. 2005. Nature.).
