比起黑猩猩与人猿，人们对同为濒危灵长动物的眼镜食叶猴的关注非常有限，自然也不了解食叶猴正因人类非法喂养与栖息地被瓜分，其生存形态遭破坏。身为食叶猴保育计划主持人的叶茹琳，为了保育食叶猴，除了到森林实地考察外，也策划户外导览，让民众认识食叶猴也教育群众，人类与动物共存的重要性。
Compared to chimpanzees and orangutans, white-eyed langurs are a much lesser known species of endangered primates, consequently most people do not understand that white-eyed langurs' natural habitat has been jeopardized to fulfill human needs. As the leader of the conservation project, Jo Leen Yap carries out her observation in the forest. Besides that, she also organizes guided outdoor tours to raise public awareness towards langurs, and also to educate the public about the importance of coexistence between humans and animals.
