The thesis examines environmental communication from within an enquiry perspective. Taking my lead from the emerging literature on science communication, I argue that the communicational obligations and permissions implicit to successful science communication can be used to help develop a successful method for environmental communication. Success in environmental communication is measured in terms of how well our method enables us to inter-communicate with the being of an environment. As an environment is an evolving, dynamic process, this leads me to define environmental
communication as any communication with an environment that seeks to find out something new about an environment. This definition allows me to argue the general thesis: In order to be effective in environmental communication, we must use a method of communication that enables us to maintain an ongoing flow of dialogic enquiry with the being of an environment.
In arguing for the above position, aspects of Charles S. Peirce's semiotic logic are introduced and discussed with reference to the issue of ' environmental problems' . Environmental problems are found to be at root disconnections between the sign use of humans and the sign use of an environment. As such, person-environment disconnections are revealed by the dissent of an environment. I call dissent the first grade of environmental concern. I then argue that two additional grades of environmental concern are required to adequately address the issue of person/environmental disconnection. To reveal the social structures relevant to an environment's dissent, the dissent must be opposed by what is already known about an environment. This creates conflict, which I call the second grade of environmental
concern. To determine whether conflicts can be dissolved by new ways of thinking and acting in the world, I argue that explanations derived from environmental conflict need to be tested at a third level of concern, which I call enquiry. These three grades of
environmental concern ( dissent, conflict, enquiry) are discussed and applied to issues of enviromnental disconnection (rainforest logging and toxic pollution). It is concluded that a semiotic approach to environmental communication offers insight into how dissent, conflict, and enquiry function as a system for environmental communication.
