All three factors contributed to the decline and extinction of black-footed ferrets. Habitat destruction has reduced the carrying capacity of ferrets, making it harder for them to find food and shelter. Lethal diseases like canine distemper have killed many ferrets directly or weakened their immune systems, making them more susceptible to other infections. Increasingly fragmented ferret populations were more likely to go extinct because they had fewer opportunities to mate, find new habitats, and avoid genetic drift. Therefore, it's necessary to address all three factors to conserve black-footed ferrets successfully.
