Recognizing animal personhood in compassionate conservation

Conservation Biology, Volume 34, Issue 5, Page 1097-1106, October 2020., 2020
Abstract Compassionate conservation is based on the ethical position that actions taken to protect biodiversity should be guided by compassion for all sentient beings. Critics argue that there are 3 core reasons harming animals is acceptable in conservation programs: the primary purpose of conservation is biodiversity protection; conservation is ...
