Chapter Meeting

Almost every living thing on our planet uses the cycle of light and dark to trigger life processes. Artificial Light at Night (ALAN) and light pollution interrupts this cycle. This program helps us understand the effects of light pollution on living things, including ourselves, and how we can protect dark skies for humans and wildlife.
