hello friend that is so interesting topic, it is said that drones are increasingly common in the US skies, are used for recreational, commercial or conservation projects, and that is why scientists are beginning to wonder how they affect the wild life in my opinion is good and are a great tool to control the population of a species and determine their habitat, and allow poachers to fight locating them, but we must take into account that animals are scared and causes stress. Blessings.
