Source: https://insite.ipwea.org/the-urgency-of-controlling-light-pollution/ Light pollution is defined as the inappropriate or excessive use of artificial light at night, and it is the fastest growing pollutant on the planet. Whilst astronomers lament the loss of stars, preventing over 80% of the world’s population from access to a natural sky, light pollution’s impacts are far more reaching. At...
