Figure 2. Effect of human presence on perception of chimpanzee population status and appeal as pets.

Detailed legend: The top bars display the proportion of survey respondents that agreed that wild chimpanzee populations were healthy/stable when viewing one of two versions of a composite image. In one version of the image, an adult human male was shown standing adjacent to the chimpanzee. In the second version, the chimpanzee was shown without any human present. The bottom bars display the proportion of survey respondents that agreed that chimpanzees were appealing as pets after viewing one of the same images with humans present or not present.
