Jamieson's style of philosophising combines common-sense thinking and rigid philosophical analysis and is scientifically informed. He articulates interesting links between different thinkers. Moreover, he does not merely focus on fascinating theoretical questions but also analyses key concepts (sustainability, ecosystem health, value) in environmental discourse, investigates important case studies (zoos, animal experimentation, global warming, biotechnology) and formulates considered value judgements. As a result his philosophical essays are exceptionally accessible to and interesting for philosophers and non-philosophers alike. In brief, what one may expect of environmental ethics at its best.
