Microbes are usually perceived as bad due to their association with diseases and illness. But there are also “good” microbes that provide many benefits in various areas. From bacteria in your guts to protozoans that aid in nitrogen fixation, microbes are proving to be one of the most useful organisms on the planet.
Even the oxygen in our atmosphere was produced by tiny microbes called cyanobacteria billions of years ago. Our human body functions the way it does because it hosts tens of trillions of bacteria – both on the surface and inside. And most of them are very important for our survival as they aid in digestion and provide immunity.
