When we create sustainable food on the moon: Lunar closed-loop food productions 

Lunar closed-loop food production is essential for sustainable habitation on the Moon, utilizing processed regolith for plant growth. Hydroponic and aeroponic systems optimize nutrient delivery, while biosphere integration ensures waste recycling through composting, algae cultivation, and oxygen generation. Genetically engineered crops with resistance to radiation and low water needs will enhance food production, supported by hybrid soil systems blending processed regolith with biochar and microbes. Symbiotic ecosystems incorporating insects and aquaponics will create efficient protein sources and nutrient cycling. Controlled greenhouse environments with artificial lighting will maintain optimal growth conditions. This closed-loop system will not only sustain lunar inhabitants but also pave the way for extraterrestrial colonization.
