Mycorrhizae, legacies, and architecture are all essential components of a healthy and sustainable environment. Mycorrhizae is a type of symbiotic relationship between plants, fungi, bacteria, and other organisms in the soil. Legacies refer to the past experiences that shape our present-day communities. Finally, architecture is the design process for creating physical structures such as buildings and bridges. All three have an important role in sustaining life on Earth and providing us with a safe place for living.
