On our planet’s largest island lives a population of just over 55,000 people, to whom football is more than a national sport. It's the reason Greenlanders keep fighting. Despite having less than 6 months a year to play outdoors, a national team that FIFA refuses to recognise, and a national championship that lasts just one week each summer, football is at the heart of every town across this ice-strewn country. Meanwhile, Greenland is changing rapidly. Traditional livelihoods and Inuit culture are under threat. Through the long, dark, Arctic winters, Greenlanders learn to adapt to the impacts of climate change. In association with BBC Studios Natural History Unit & Moondance Foundation.
