Marrs, R. (2007). Human Preferences for Species Conservation: Animal Charisma Trumps Endangered Status: Science Direct.
Robert H Marrs, writer of Human Preferences for Species Conservation: Animal Charisma Trumps Endangered Status, observed the likeliness of humans to donate more money to species more similar to humans, regardless of whether or not that animal is more endangered. The purpose of this opinion piece was to express the reality of what order these animals are conserved in. It emphasizes that charismatic species are more likely to be chosen. The target audience is anyone interested in the patterns of monetary donations towards animal conservation and can be useful to anyone interested in animal conservation.
