Deep inside Indonesia's Ujung Kulon National Park, a motion-activated camera catches the world's "rarest" mammal, the Java rhino, as it gingerly steps into a clearing, calf in tow.
Once the most common rhino in Asia, the Javan is now critically endangered. Only 40 are left in the world, none in captivity.
Man remains the adult rhino's sole predator. Poachers take aim at the remarkable beast for its horn, which serves as an unfortunate ingredient in traditional Chinese medicine. Thanks to misinformed witchdoctors, a single environmental disaster could wipe the species off the planet.
For a good idea of how many Java rhinos are left roaming the earth, consider that if the entire population ventured off on a road trip, they would barely sell out a Greyhound bus.
If their destination's set for safe havens, we'll gladly pay the fare.
