Environmental Campaigner; understanding about 'Space-ship' Earth at school, 50 years ago!

It seems that Chris Chadwell was expressing concern about our environment during his school days; he showed interest in plant identification even in his primary school. All this, almost 50 years before Greta Thunburg!

An essay written aged 14 at the Barclay School, Stevenage - expressing his concerns about the environment - almost 50 years later he witnessed damage to the Slough Arm of the Grand Union Canal near his home in Langley, Slough. Odd that, less than a decade later Chris should be team-leader of a survey of riverside vegetation in Wales (see: https://sites.google.com/a/shpa.org.uk/main/team-leader-survey-of-riverside-vegetation-wales)
