Without a basic resource like metal, the development of civilization would definitely be severely restricted.
"After the Stone Age, the era we experienced was the Wood Age. It was an era that was completely different from other native civilizations."
"Due to the lack of metal, we set our sights on the plants that were the easiest to obtain. Although metal resources were scarce, the vegetation resources were extremely abundant, and there was no lack of plants with special characteristics.
"Some of us who are talented think of ways to increase the production of plants and cultivate plants with special uses. It can barely be considered a change in productivity."
"For this reason, our biological sciences have advanced quite early. Even now, biology is our forte."
