Armed with a camcorder, farmer-filmmaker-activist Severine von Tscharner Fleming spent two years crisscrossing America, meeting and mobilizing a network of revolutionary young farmers resettling the land. 'The Greenhorns' is an ode to their grit and entrepreneurial spirit, an exploration of sustainable agriculture, and an enticement to reclaim our national soil. The ninety minute feature is the culmination of well over 200 hours of original footage from all regions of the United States, as well as original animation by young urban farmer and artist Brooke Budner, and rare agricultural archival footage from the Prelinger Archives. Ultimately, The Greenhorns shows us how farmers can move out of the margins recent history has consigned them to, and back to the heart of the American food landscape.

The beauty of the Arctic is breathtaking. For as long as we can remember, the Arctic has been associated with inhospitable cold. But the climate is changing, and with it the northern polar region, which begins beyond latitude 66.5 degrees north. Climate change is now happening four times faster north of the Arctic Circle than on the rest of the planet, making the future outlook dire. At the moment it is still possible for polar bears to raise their cubs, but hunting is becoming increasingly difficult on the drastically shrinking pack ice. The disappearance of the ice also affects the marine fauna. The wintry ice bridge between Canada and Greenland is threatened with collapse. The unstoppable melting of the permafrost, which has held the tundra together for thousands of years, is worrying. But the Arctic is still one of the wildest and loveliest regions on earth. A documentary visit to the Arctic - as long as it still exists.
