Follows the story of "Grizzly Man" Timothy Treadwell and what the thirteen summers in a National Park in Alaska were like in his attempt to protect the grizzly bears. The film is full of unique images and a look into the spirit of a man who sacrificed himself for nature.

For almost three years, nature filmmaker and ecologist David Cebulla has been observing wild Common hamsters. He not only tries to learn more about the species, but also documents why hamsters are globally threatened with extinction. David travels from the western border of the distribution area in France via Germany, Poland, Austria and Hungary to the eastern border of the distribution area in the Kazakh steppe. In the process, he manages to capture some unique and fantastic images. But during the project, it becomes increasingly difficult to find animals living in the wild.

Jellyfish blooms are making headlines around the world. This is due to the damage they cause to tourism, fishing and our health. How can these creatures, which are over 98% water and have no shell, skeleton or brain, expand so rapidly?  Although this is a normal stage in the life cycle of these gelatinous animals, we have to admit that blooms have become much more frequent and massive in recent decades. We're even witnessing jellyfish populations appearing in more and more regions where fish have been replaced by them, such as off the coast of Namibia, in the Black Sea, in the Sea of Japan and in certain areas of the Baltic Sea. What causes this? Why has the role of jellyfish in the ocean been underestimated, even though they outlived the dinosaurs? Are jellyfish on their way to dominating the oceans as they once did? What if they were to be the only ones left?

Great Smoky Mountain National Park covers over 500,000 acres of breath-taking beauty: lush highland meadows, glorious waterfalls, pristine mountain streams, and one of the most biologically diverse ecosystems in the world.

David Attenborough and scientist Johan Rockström examine Earth's biodiversity collapse and how this crisis can still be averted.

For millennia, Native Americans successfully stewarded and shaped their landscapes, but centuries of colonization have disrupted their ability to maintain their traditional land management practices. From deserts, coastlines, forests, mountains, and prairies, Native communities across the US are restoring their ancient relationships with the land. As the climate crisis escalates these time-tested practices of North America's original inhabitants are becoming increasingly essential in a rapidly changing world.

Developments in the Canadian forestry industry during the 1970s are shown being carried out both as lab experiments and in the field to protect and conserve the country's vast forests. These include turning a Newfoundland bog into woodland, fostering British Columbia seedlings that withstand mechanical planting, inoculating Ontario elms against the bark beetle, devising ways of controlling fire, and more.
