How important are molds to life on Earth?
In the natural environment, molds are important and desirable because they hasten the decomposition of organic material such as fallen leaves and dead trees. Indoors, however, mold growth is undesirable.
Why is mold important?
Molds are important decomposers of dead plant and animal matter. By decomposing organic matter, molds play a big part in material biodegradation, enabling decay and rot necessary in all ecosystems, releasing carbon and other materials back into the environment where they can be reused by plants.
Are some molds beneficial?
Are Any Food Molds Beneficial? Yes, molds are used to make certain kinds of cheeses and can be on the surface of cheese or be developed internally.
What would happen if fungi didn't exist?
Without fungi to aid in decomposition, all life in the forest would soon be buried under a mountain of dead plant matter.
How fungi can save the world?
Along with bacteria, fungi are important as decomposers in the soil food web. They convert organic matter that is hard to digest into forms other organisms can use. Their strands – or hyphae – physically bind soil particles together, which helps water enter the soil and increases the earth's ability to retain liquid.

People may also be exposed to mold through the skin. Workers should be properly protected with safety equipment when remediating, or cleaning up mold after a disaster. In some cases, people may be exposed to mold through their diet.
What is the goal of the Natural History of Asthma with Longitudinal Environmental Sampling (?
