Brochures and guides: Light pollution impacts on wildlife, energy, safety, and human health

Once a source of wonder, the star-filled nights of just a few years ago are vanishing in a yellow haze. Human-produced light pollution not only mars our view of the stars – it threatens astronomy, disrupts ecosystems, affects human health, and wastes energy. The International Dark-Sky Association (IDA) has produced a range of brochures and guides designed for public use addressing light pollution impacts on wildlife, energy, safety, and human health.
