N This prepares you for the moment when you face a polar bear. In my long career of doing nature documentaries, I found grizzly bears in Alaska and silverback mountain gorillas in Uganda and Rwanda, one of which knocked me to the ground when he thought I could threaten his family. That made it no less scary when I stood less than ten yards from a polar bear, perhaps the most dangerous predator in the world.
I shot Undiscovered Worlds a documentary of the BBC broadcast on Easter Sunday together with presenter Steve Backshall. Kayaking through Scoresby Sound in Greenland, the largest fjord in the world, to study the damage caused by climate change, which melts the region's ice and destroys habitats for indigenous wildlife.
Most nights we camp in tents under the stars. We wrap ourselves in layers to ward off the bitter Arctic cold. We were acutely aware of the danger of being attacked by polar bears ̵
The sea ice around Greenland follows the same trend that has been observed throughout the Arctic. At the beginning of the year, it shrank and melted, robbing the polar bears of their best hunting life and making their behavior less predictable. As far as we were able to paddle into this beautiful land, it was clear that the location was more serious than we had imagined, and the fjord, which was usually covered in sea ice at this time of year, was a pale imitation of itself.
