Whitening the Sky: light pollution as a form of cultural genocide

Duane W. Hamacher, Krystal de Napoli, Bon Mott

Light pollution is actively destroying our ability to see the stars. Many indigenous traditions and knowledge systems around the world are based on the stars, and the peoples’ ability to observe and interpret stellar positions and properties is of critical importance for daily life and cultural continuity. The erasure of the night sky acts to erase indigenous connection to the stars, acting as a form of ongoing cultural and ecological genocide. Efforts to reduce, minimise or eliminate light pollution are being achieved with varying degrees of success, but urban expansion, poor lighting design,and the increased use of blue-light emitting LEDs as a cost-effective solution is worsening problems related to human health, wildlife,and astronomical heritage for the benefit of capitalistic economic growth. We provide a brief overview of the issue, illustrating some of the important connections that the Aboriginal and Torres Strait Islander people of Australia maintain with the stars, as well as the impact growing light pollution has on this ancient knowledge. We propose a transdisciplinary approach to solving these issues, using a foundation based on indigenous philosophies and decolonising methodologies.
