PGE is the only possibility to resolve population, habitat and food conflicts on Earth

The steric overlap of green PGE has become the only possibility for humans to resolve the increasingly tense population, habitat and food conflicts on Earth. Endless artificial 24-hour sunlight planting in unit planting volume is far better than natural sunlight planting only in unit planting area. It can fully meet the energy needs of the whole earth and the photosynthesis of various crops. The land is multiplied due to its overlap, freeing up a lot of space for building HOS flats. Agricultural production and industrial production tend to be unified, and no longer need to rely on the sky to eat.
