Dr Catriona Russell, Assistant Professor of Ethics in the School of Religion at Trinity College Dublin, takes us on a journey back to the meaning of the word techné so that we can be re-introduced into what the etymology of the word technology is. She then discusses the current marketisation of urban life and whether or not the idea of sustainability is authentically expressed  in attempts to introduce technology in the city that will off-set our human behaviours that contribute to environmental degradation. Catriona’s lecture provides much hope as we seek to navigate the ethical questions and choices that face us as we embrace technology in a world which also requires ecological conversion and simplicity of living.  There is much food for thought also in the phrases that Catriona uses in her lecture. The ‘commodification of the sky is something we will all need to consider about going forward…’.  A must listen!
