The plan is to control supply. Although we would simultaneously reduce both supply and demand. Cut supply by refusing to produce fossil fuels. Reduce demand by refusing to produce nearly anything except necessities—food, medicine, shelter. Both demand and supply would be slashed sharply. People would have less stuff but much more time—which means more LIFE.
This is a whole new culture worldwide replacing greed and obsession with excessive goods with appreciation for enjoying life, Nature and each other’s company.
