Over the course of civilization,humans have increasingly expanded their freedom to live a better *** comparison with the primitive society,our modern society has many more choices of life-supporting resources,such as yearround food supply,permanent shelters,diverse energy sources,and effective preventive and curing ***,our society is currently still heavily relying on the resources provided by Mother Nature,which cannot meet the future global needs in terms of both quantity and quality under the pressure of population growth,natural resource reduction,and environmental *** example,the food sources originating from plants,animals,or microbes do not have the nutrition balance for optimal human health[1–3].Climate change and environmental deterioration threaten the food security[4–6].Increasingly,infectious diseases(e.g.,HIV/AIDS),genetic diseases(e.g.,cancer),and improper lifestyle-related disorders(e.g.,obesity)become more prevalent and remain challenging to be prevented,controlled,and *** medical technologies and modern medicine development are also meeting the ceiling.
