Fungi are everywhere. In the air, in the water, in our bodies, in the trees, in the ceilings of our bathrooms, underground. They can be mushrooms (edible, medicinal, hallucinogenic, or very poisonous), or take other simpler forms, such as molds. They can trigger illnesses, but they can also produce antibiotic remedies, such as penicillin, or help ferment amazing cheeses and breads. Could they also be the future of packaging and building materials?
