Earth may seem like the most hospitable planet in the solar system. But look again. Startling new discoveries reveal the blue planet has been plagued by more chaos and destruction than scientists once imagined. Stand on the Earth billions of years ago as a primitive planet called Theia slams into it. Shiver as our entire globe is frozen over like a gigantic snowball. Feel the heat as mammoth volcanoes scorch the landscape and darken the sky. From a cosmic gamma ray burst frying away the ozone layer to an Everest-size asteroid slamming into the ocean, we'll reveal new information about how these unparalleled events drove life to the brink of total extinction. Out of this continuous devastation, how has our planet--and life--got to where it is today? Are the worst days behind us--or lurking in the distant future?

The Nazis had relentlessly persecuted German and Austrian Jews, reducing their rights, expropriating their property, choking off their livelihoods, declaring them parasites, not citizens and on the evening of November 9, 1938 Kristallnacht, the Night of Broken Glass, Hitler unleashed Nazi mobs on Jews in cities and towns all over the newly expanded Germany, beating, burning, raping, killing, hoping to drive them all out of their country. Hundreds of thousands of German and Austrian Jews were now desperate to escape the Nazis. They knew their only hope lay in flight into friendly European countries or across the ocean to the United States.
As WWII begins, Americans are divided over whether to intervene against Germany. Some individuals and organizations work tirelessly to help refugees escape. Germany invades the USSR and secretly begins the mass murder of European Jews.

Africa's wildest river is home to the most spectacular wildlife. Hippos fight for territory while herds of elephant, water buffalo and zebra depend on it for life. In the wet season the rains burst the riverbanks and everyone, including people, must move whilst fish swim through the villages. In the dry season the creatures fight over the few pools of water while predators prowl. At its heart it plunges over Victoria Falls and into wild ravines before draining into the Indian Ocean, where storm clouds cycle the water back into the heart of Africa.
