Julian Huxley was one of the first to popularise the term biosphere. In 1969 he and Max Nicholson publicly stated:
“…the earth supports a realm of living creatures, plant and animal, which is gradually becoming known as the ‘biosphere’. Emerging from that living layer, the human species has quite lately begun to create, as Teilhard de Chardin pointed out, an intangible but even more significant ‘noosphere’, or realm of human feelings and ideas. This agency of psychological change is steadily evolving toward greater universality and continuity all the time”[“Times”, 7.10.1969].
