Tackling Light Pollution

Light pollution or excessive use of external artificial light is a form of energy waste that affects human health, wildlife behavior and our ability to observe stars and other celestial objects. At night, the light interrupts sleep and disrupts the circadian rhythm, the internal clock of twenty-four hours that guides activities and affects physiological processes. The effects of light on wildlife, in addition to disturbance of circadian rhythms, include restriction of movement and impaired reproduction. Plant life is also affected. Thus, light pollution is particularly concerning within ecological corridors and areas of nature conservation. Good practices for light pollution control have already been included in the Chelsea Masterplan. In 2024, ACRE is planning to assess the state of knowledge and attitudes towards light pollution and its impacts and the current state of practices. Also, an awareness session with Mr. Robert Creed, CEO of Canadian Scotobiology Group and Ecolights and a renowned expert in light pollution, is planned for 2024.
