Ethical perspectives for public and environmental health: fostering autonomy and the right to know.

In this paper we develop an ethical perspective for public and environmental health practice in consideration of the "right to know" by contrasting consequential and deontological perspectives with relational ethics grounded in the concept of fostering autonomy.

We discuss three major concerns with this perspective: respect for persons, justice, and ignorance.
