A versatile fern called azolla could revolutionize food production by offering a sustainable source of nutrition and aiding in carbon capture, according to recent research. In short:Azolla, a rapidly growing fern, holds potential as food, fertilizer, and biofuel, but requires further research to ensure it's safe and nutritious. Carolina azolla, a specific species, has lower levels of polyphenols, making it a better candidate for human consumption after processing. Beyond nutrition, azolla's ability to fix nitrogen and capture carbon could significantly benefit agriculture and the environment. Why this matters:Azolla's rapid growth and environmental benefits could provide a crucial alternative in times of food scarcity and play a role in sustainable agriculture.
