At least 18,000 animal species globally are threatened with extinction: they’re listed as vulnerable, endangered or critically endangered by the IUCN, the global wildlife conservation authority.

This triggered one county to kill four wolves of a pack who had become reliant on livestock as a food source. Some ranchers are now adopting nonlethal deterrents, such as faldry (strips of fabric hung on a fence), drones blaring loud music, and electric fences, to keep wolves at bay, reported Mongabay’s Spoorthy Raman.
