Respecting the Circle of Life is based on Protection Motivation Theory (PMT).
PMT is a social cognitive theory that emphasizes the balance between pressures to engage in a risk behavior (social and personal rewards), risks involved (severity of the undesired outcome, vulnerability), and considerations of the alternatives (how well the alternatives help avoid undesirable outcomes; ability of the youth to employ the alternative behavior; and social, personal, or other costs associated with employing the alternative).
