In the United States, we tend to think of algae as something that we peer at through microscopes during 4th grade cellular biology lessons or as the morphing clouds of green goop that creepily touch our toes when we take a dip in the lake. While often dismissed as an unimportant nuisance, algae are in fact a fascinating group of microorganisms, which use the simple components of sunlight, carbon dioxide and mineral water to robustly sustain life and reproduce at incredible rates. They are in essence, nutritionally complete microcosms of the energy systems that support us all- a blueprint for life as we understand it to be. In many cultures around the globe, different types of algae are revered as sacred superfoods, enjoyed as a spread over tortillas or dried and served with grains and vegetables.
