why these words could be used to describe jane goodall: wanting to observe and be around the chimpanzees not only to end curiosity, but help people learn more about them so that this knowledge could be used later when learning how to protect them could be considered just and morally right. being able to accomplish so much and just be around happy chimps and know that people support what she did could have made her rather jubilant and celebratory, especially when learning new things about chimps that others had not known before then. she seemed to be an overall happy person, especially around the animals, and people have never really described her as a miserable person to be around. this could make her joyful.
