With resource shortages looming and climate change a topic of intense discussion, it is becoming increasingly important for people to find ways to reduce their day-to-day consumption and carbon footprint. Greg Foyster’s Changing Gears seeks to explore the question of how to do so through the author’s own interesting, and no doubt exhausting, cross-country journey toward a greener way of living. Setting out to cycle from Melbourne to Cairns via Tasmania, which makes more sense in context, Foyster and his partner used the journey to force themselves into the sparse life of bicycle travellers, while visiting and interviewing a number of prominent experts and practitioners of conservation, green living, and social dynamics.
