Scientists in the UK have discovered the biochemical steps by which grass peas produce a poison, causing irreversible paralysis in malnourished individuals. However, they are optimistic that they can create safe versions of grass peas in the near future and provide the planet with a valuable crop. Grass peas have the potential to play an important role in extreme climate conditions, as they have deep roots that improve soil quality and can survive in drought, flooding, and saltwater intrusion.
