I would however suggest that there is a need for a model for people to live within a close social structure without
becoming detached from nature in which the land on which we live is involved with supporting us through what might be called urban agriculture,
vertical farming and the affiliated processing of clean water, natural dynamic energy generation like wind, solar and water, and cheap / easy / affordable transit all tied - up with great education and health care.
One study has calculated that if present trends continue, 1.8 billion people will be living in absolute water scarcity by 2025, while a full two thirds of the human population will face water stress.With agriculture currently accounting for some 72 % of human water use it seems likely that such steps to reduce water consumption will
become a desirable provision of
vertical farming in the future.
