S4 E1 | Elephant Conservation and Tigerfishing

Kyle and Jeff return to South Africa's Kruger National Park to explore the challenges of elephant overpopulation. Joining biologists and veterinarians, they track down a bull elephant as part of an effort to determine whether chemical castration could help control population growth. Then, they head to Lake Jozini in pursuit of one of Kyle's bucket-list fish: the toothsome tigerfish.
