Geobiology is a fascinating and interdisciplinary field of science that combines the study of geology and biology. It focuses on understanding the interactions between the Earth’s physical and biological processes, and how these interactions have evolved over time to shape our planet’s surface and its inhabitants. One of the key principles of geobiology is the concept of “life as a geological agent.” This means that living organisms, from the tiniest microbes to the largest animals, play an active role in shaping the Earth’s surface.
