These possible harms can be outweighed by the gains we make as humanity from protecting these species. It is important to note that the way we benefit from protecting endangered species extends benefits not just to the current generation but to future generations in terms of the preservation of biodiversity for scientific and aesthetic reasons. By contrast, allowing farmers to hunt to extinction species which are a threat to their livestock is only a short-term gain which applies almost exclusively to the farmers themselves and not to humanity as a whole.
