The author highlights the emotional and ethical implications of wildlife destruction and displacement, illustrating the contrast between the perspective of those who justify such actions for economic gain and the intrinsic value of wildlife. This creates an emotional appeal to the audience. However, there are also elements of logos in presenting the financial contrasts (e.g., the ecotourism value of rhinos vs. the trafficking values), but the central thrust of the argument appeals more to emotions and values.
