Introduction

Guan Zhong said, “When there is a lot of rice in the warehouse, people will have morality. If people have sufficient clothing and food, they will be able to understand the difference between honour and shame.” Food, clothing, and housing are three basic things for human life and most of them have been obtained from the plant biomass available from the surrounding human activities. Furthermore, philosophical concepts and social structures in ancient societies were established depending on the sufficient production of staple foods. It can be said that the civilization of human society has been based on a progression of a wide range of biomass utilization. For example, various necessary goods, such as stationary, were required to record historical events and philosophical ideas. To maintain the social systems in ancient societies, a memory system for storing a large amount of data was needed.
