More than 800,000 km2 of the Arctic were affected by human activity in 2013, according to an analysis of satellite-derived data on artificial light at night. On average, 85% of the light-polluted areas are due to industrial activities rather than urban development. According to the international team led by UZH researchers, the results are crucial for sustainable development and nature conservation in this highly vulnerable region.
