The highest mountain range in the world, the Himalayan range is far reaching, spanning thousands of miles, and holds within it an exceptionally diverse ecology. Coniferous and subtropical forests, wetlands, and montane grasslands are as much a part of this world as the inhospitable, frozen mountaintops that tower above. The word Himalaya is Sanskrit for abode of snow, fitting for a stretch of land that houses the world’s largest non polar ice masses. Extensive glacial networks feed Asia's major rivers including the Ganges, Indus, and Brahmaputra. More than a billion people rely on these glacier-fed water sources for drinking water and agriculture. The Himalayas are not only a remarkable expanse of natural beauty. They're also crucial for our survival.

This film, three years in the making, The remote forests of Kalkalpen National Park in Austria, the largest area of wilderness in the European Alps, have been left untouched by humans for nearly a quarter of a century in order to return to their natural, primeval state. The landscape regenerates itself in dramatic cycles of growth and decay, and this bold hands-off method of conservation yields salient results: the lynx, absent from the area for 115 years, has returned.

A journey to seven of the most geographically dynamic locations on earth. The film features spectacular land forms, diverse wildlife and the people and cultures indigenous to these places. Distinct geographic places include the great island of Madagascar, home to unique limestone pinnacles and the playful lemur; and the greatest desert—the Namib—home of the largest sand dunes in the world that tower majestically over its western border, the Atlantic Ocean. Other locations featured are the great icecap of Greenland, Iguazu Falls in Brazil, the Okavango Delta in Botswana, the Chang Tang Plateau in Tibet, and the Amazon River in South America.

Over a 10-year period, more than 200 people have disappeared from the area surrounding Tanzania's Lake Tanganyika. At first, the disappearances were attributed to a serial killer or tribal warfare, but scientists eventually discovered that the culprit was a huge, nearly 100-year-old crocodile dubbed "Gustave." This fascinating PBS documentary chronicles scientists' efforts to trap Gustave and move him to a nature preserve before he strikes again.
