Introduction In today’s world, two phenomena are particularly prominent – growing concern for environmental protection and the ubiquitous spread of the English language. Industrialisation and economic development have seriously damaged the environment locally, nationally and globally, causing depletion of natural resources; loss of plant and animal species; pollution of waterways and the atmosphere; human illness; and changes in climate (DeSombre 2007; O’Neill 2009). The need to resolve these issues and prevent further damage to the environment has been widely recognised and attracted considerable support around the world (O’Neill 2009). So influential is environmental protection that it has begun to shape the policies, behaviour and practices of governments, organisations, industries and publics around the world (Mol 2010).
