I'm delighted to discover that #ManAndTheEarth by #PatrickDuncan (1975), was reprinted in 2015 & is still in print. I have sent off for a copy & will review for '#Greeneralia' in due course.

His 'Geism' was understood to be introducing a philosophical element into the ecological movement. But seen from 2023, his primary insight was about uniting #Global South/North to act in time to #saveplanetearth.

An idea whose time has definitely come?
