"Certainly in the case of the treatment of animals, the scales are heavily weighted against us. Although it is true that some humans do some good for animals, much of this is merely rescuing animals from the maltreatment of other humans. At the level of the human species such benefits cannot be used to offset the harms. If there were no humans to inflict the harms, these benefits would not be necessary. Of course, humans do bestow some other benefits, such as veterinary care for their companion animals. However, the number of animals affected and the amount of good done is massively outweighed by the harm the human species does to non-human animals."
