It is easy to be grossed out by fungi or worry about its impact on our health. While both are valid concerns, fungi and mold are actually important to our everyday lives. Like bacteria, fungi exist almost everywhere on the planet. They are hardy organisms the thrive in places you might not expect. Also like bacteria, they are essential in the breakdown of dead and decaying matter. One important group of fungi that does this is known as saprophytes. These fungi use decaying matter for nourishment, and without them breaking down organic matter throughout the environment, life on Earth would be quite different. Without fungi, the world we know could not exist.
