the reason half the planet eats is a factory that pulls bread from thin air
means A substance, natural or manufactured, added to soil to supply the nutrients plants need to grow.
from From Latin 'fertilis,' meaning fruitful or productive — itself rooted in 'ferre,' to bear or carry, the same verb that gives us 'fertile.' English added the busy '-izer' to turn the quality of being fruitful into the act of making something fruitful. The word stayed humble for centuries — meaning manure, ash, anything that fed the dirt — until the early 20th century, when the Haber-Bosch process let chemists pull nitrogen straight from the air, and 'fertilizer' came to carry the weight the essence hints at.
