This inspiring series celebrates the human-animal bond by telling uplifting stories about shelter pets and the people that help them. This episode, hosted by anthropologist Jane Goodall, features shelter dogs that are trained to protect endangered species. We follow the dogs from the day they are rescued to their deployment in Zambia where they are helping prevent the poaching of elephants and rhinos. Also: a high school cross country team takes shelter dogs for a run as part of their practice.
More than 2,000 years ago, the thriving city of Petra rose up in the bone-dry desert of what is now Jordan. An oasis of culture and abundance, the city was built by wealthy merchants who carved spectacular temple-tombs into its cliffs, raised a monumental Great Temple and devised an ingenious system that channeled water to vineyards, bathhouses, fountains and pools. But following a catastrophic earthquake and a slump in its desert trade routes, Petra’s unique culture faded and was lost to most of the world for nearly 1,000 years. Now, in a daring experiment, an archaeologist and several sculptors team up to carve an iconic temple-tomb to find out how the ancient people of Petra built their city of stone.
