|Purpose||Preserve Mata Nui landscape, create tools|
|“||Farming lava is one way we keep Mata Nui green and healthy. When lava cools, it makes the best soil. With our farming, Le-Koro grows green, Ga-Koro's waters bountiful, and Onu-Koro's mines rich. But like the two brothers, the fire of the Mangai is both a force of creation, and a force of destruction. To farm lava takes great Courage.||”|
–Aft describing the occupation of Lava Farming, Mata Nui Online Game II: The Final Chronicle
Lava Farming was a type of work usually performed by Ta-Matoran on Mata Nui. These Matoran farmed lava by draining it out of the Mangai Volcano and using it for different applications, such as hardening it to create tools, or making soil from slightly cooled lava.
