'ecologically-affected' originates from the combination of 'ecology' and 'affected', where 'ecology' is derived from Greek 'oikos' meaning 'house' and 'logia' meaning 'study of', and 'affected' from Latin 'afficere' meaning 'to influence'.

'Ecology' evolved from the Greek 'oikos' and 'logia', while 'affected' transformed from Latin 'afficere' to Old French 'affecter', eventually becoming the modern English 'affected'.

Initially, 'affected' meant 'to influence', and this meaning has largely remained the same in modern usage.
