Scientists in the former Soviet Union called for an ecological civilization in 1984. The idea was taken up in China by Ye Qianji in 1987. The Chinese as a whole rejected a separation of man and nature in the sense that one could become whole without the other. This aspect of Chinese traditional culture had a great impact on Thomas Berry’s thinking. Robert Woolf prefers the term “culture,” the necessarily local way a group of people have learned to live in balance with each other and with their local environment.
