Manure creator for the farming world of Giggleswick VII
The farming planet of Goggleswick VIII grows 50% of the food shipped to Deep Space outposts and Mining colonies. The entire planet has vast fields of crops, and pasture for animals.
They need a constant supply of manure to grow the crops, and the local animals don't create nearly enough. They are in need of people to dedicate their lives to eating and creating manure.
