Now to the global outrage tonight after an american tv host proudly posted pictures of her latest kill. Abc's lana zak is in south africa. Reporter: Melissa bachman is a self-professed animal lover. An absolutely beautiful animal. Reporter: But she also makes a living hunting animals down. Check out the size of this rack! Reporter: She's killed zebras and bears, but it's this image of a lifeless lion that has sparked a global outrage. And even though her actions are perfectly legal -- because these kills are being made on a private hunting preserve -- the disturbing picture has prompted some 60,000 to sign a petition demanding she never be allowed to return to south africa. Melissa should be banned from south africa and not just her, other people that do the same thing. Reporter: This man teaches conservation through safe interaction with lions. The last 20 years, lion populations have gone from over 200,000 to less than 50,000. Why would anyone want to come out and decrease those numbers even more? Reporter: For bachman, the hunt is all about her cable show, "winchester deadly passion." I've got a wonderful wart hog. Reporter: We received no comment when we reached out to bachman and her show this weekend, but online, plenty of outrage. One critic saying, "it's not the hunting part that people have a problem with. It's the total lack of regard for creatures that aren't meant to be eaten or hunted. And her actions come at a particularly poor time, david. A new report says if current trends continue, the population of lion living in the wild could be gone in at little as ten years.
