Microbes are hungry. All the time. And they live everywhere, in enormous numbers. We might not see them with the naked eye, but they are in soils, lakes, oceans, hydrothermal vents, our homes, and even in and on our own bodies. And they don’t just hang out there. They are always eating. All together, they eat so much that they influence the elemental cycles of the entire planet.
