'ecologically-changed' originates from the combination of 'ecological,' which comes from the Greek word 'oikos' meaning 'house' or 'environment,' and 'changed,' from Old English 'ceosan,' meaning 'to choose or decide.'

'ecological' evolved from the Greek 'oikos' and 'logos,' meaning 'study of the house/environment,' while 'changed' evolved from Old English 'ceosan' to Middle English 'chaungen,' eventually becoming 'change.'

Initially, 'ecological' referred to the study of environments, while 'changed' meant 'to choose or decide.' Over time, 'ecologically-changed' came to mean an environment that has been altered.
