Exploring the potential of azolla as a future food source

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.

Matt Simon reports for Wired.

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.

Key quote:

"I’m not out here saying everybody should go eat this stuff right away, but boy, it’s got so much potential."

— Daniel Winstead, research technologist at Penn State.

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. In this 2017 essay, Robyn Alders and Richard Kock argue that it’s time to rethink our food system and acknowledge our responsibilities to renewal of resources and the rights of existence for all life forms on Earth.
