Science and nature writer, Sharon Guynup, and National Geographic photographer, Steve Winter, answer these and many more questions about nature's greatest, most beautiful, and endangered predator, the tiger.

Over 2 MILLION views on YouTube and a standing ovation on Britain’s Got Talent represents an unprecedented success for 7 year old Wildlife Poet Olivia. What other conservationist has delivered their message to so many and looked so charming doing it?

Olivia Binfield is a conservation hero in my eyes, and I think you will think so, too. Today we get to meet and talk to Olivia and her mum, in England, about how Olivia did it, why she did it, and what she is doing now to help save animals. And ofcourse, she wants to grow up to be a zoologist.

When you want information about the tropical rain forest, maybe diverse information like, the effects of rainforest destruction on climate change, the mining practices for gold in Brazil, the breeding behavior of jaguars, or of the use of drones in monitoring wildlife in Borneo - where would you go? Online, for sure - but to which website? Well, teachers, students, company CEOs, academic PHDs, environmental NGOs, and government officials have been going to the most visited website on the subject of Tropical Rainforests in the world: Mongabay.com. Mongabay was started 14 years ago by a college student and is today, still piloted by its creator, Rhett Butler.

Today we meet the amazing DeWet Du Toit. He is the one I call, the Real African Tarzan! That's because he does live in Africa, and much of the time he lives as Tarzan lived - in the jungles, climbing trees, diving off waterfalls, and cavorting with elephants and pythons. This Tarzan is complete with gorgeous muscles, a stylish loincloth, and a love for wildlife. This guy is the real deal. It's taken me months to arrange, but we will finally get to talk to this modern-day Tarzan. DeWet is an actor determined to play Tarzan in the next live action film. He is also a film-maker and excellent at internet marketing, too. He is a man, who, against all odds and occasional ridicule, is following a dream. Right now, we are connected to DeWet in Africa, and we are going to explore his dream, his life, and get to know, today's TARZAN!

Hello, and welcome. We are going to talk with our Field Correspondent, Stephanie Arne from the Honolulu Zoo about Sloths. If you were lucky enough to spot one in the trees of the South American rain forest, it would look like a stringy clump of moss and algae in the branches overhead. It wouldn't seem to move, because they move so slowly. And because they live upside down, hanging from tree branches, you wouldn't recognize one as being an animal at all. But when you get to know a sloth that has been all cleaned up, you find that they are delightful creatures and down-right cute. Well, thanks to Stephanie, we are going to get to know Sloths.

Now we get to have a conversation with the one I call, a Rock Star of conservation, the Orangutan's best friend - Allie Boyer. She is a 14 year old who cares about wildlife and decided to DO something about species extinction. Allie has raised thousands of dollars to help save Orangutans! I consider Allie, and her mom, Pam, to be inspirations for all of us . And Allie has proven that children can do important things to help save endangered species. Share this story with your children. In fact, Allie is looking for helpers. She will be happy to show you how to set up a chapter of her fundraising project, she calls, Purses for Primates. Just ask her!

So what did happen in 2012? As a fan of Jungle Deep, you will know that we had an Earth Summit this summer. But there were several other important conferences this year, too. We will hear about:

- The IUCN Congress - the International Union for Conservation of Nature get-together about species conservation which took place in South Korea in September.

- The Biodiversity Convention in India, in October, producing new numbers about the great contribution of Indigenous Community Conservation Areas.

- The Pacific Islands Leaders Forum in August, and the dramatic increase in protected ocean areas.

- The United Nations Convention on Climate Change in Qatar, in December

This is Part 2 of our conversation with character actor and star of the 1959 Hollywood movie, Tarzan, the Ape Man, Denny Miller! In part 1 we got to hear about Denny's early experiences in Hollywood and playing the part of Tarzan. We heard that the Asian Elephants used in the movie had to wear rubber ears to look like African Elephants, that riding elephants entailed using ladders to mount them and since a saddle was out of the question, Tarzan has to worry about a bad chaffing problem as he wore only a loin cloth while sitting on the elephants rough and bristly back. And apparently Tarzans the world over are vulnerable to occasional sudden nasty bites from their co-stars and friends, the chimpanzees.

How many of us would love to make a living exploring exotic places while starring on our own television adventure show with a huge audience?

Mutual of Omaha has held this video contest on YouTube, visited by over 5 MILLION viewers, to find the right person to host a 50th anniversary webisode of Wild Kingdom. Our three finalists are seasoned explorers, travelers and wildlife enthusiasts. Hear their stories and decide which one you would like to see be the next Wild Kingdom Wild Guide.

This is a particularly fun and funny episode today. We are going to get the inside scoop about what it is like to be a Hollywood Tarzan, through our conversation with actor Denny Miller. Move over Spock! Did you know that the elephants in the Tarzan movies were the first to wear ear appliances? Did you know that Tarzan used a ladder to get on top of his elephant? Did you consider that with an elephant's rough hide, there quickly develops a severe chafing problem when you are wearing only a loincloth? How about a loincloth made of seashells?? Yes, Tarzan wore one but it was scrapped because it was too noisy - he could not sneak up on the bad guys! Is it true that Tarzan had to be constantly ready to punch his cute little co-star in the nose? What?! Yes, hear all about this and more as we speak with successful character actor and Tarzan star, Denny Miller
