'ecologically-damaging' originates from 'ecology,' which comes from the Greek word 'oikos,' meaning 'house' or 'environment,' and 'damage,' from Old French 'damager,' meaning 'to harm.'

'Ecology' evolved from the Greek 'oikos' and 'logia,' while 'damage' transformed from Old French 'damager' to Middle English 'damagen,' eventually becoming the modern English 'damage.'

Initially, 'damage' meant 'to harm or injure,' and this meaning has largely remained the same in modern usage.
