According to the International Dark-Sky Association (IDA) – founded in 1988 and based in Tucson, Arizona – light pollution is increasing at a rate two times that of population growth, and 83% of the global population lives under a light-polluted sky. That’s why the group has established an International Dark Sky Week, which in 2022 falls on April 22 to 30. Goals for the week include turning off unneeded exterior lights and considering leaving them off all year long. The group also hopes you’ll learn the stars and constellations, and teach them to others, and join the global dark sky movement to protect and celebrate our shared heritage.
According to the IDA:
It may seem harmless, but light pollution has far-reaching consequences that are harmful to all living things. Effective outdoor lighting reduces light pollution, leading to a better quality of life for all. The dark sky movement is working to bring better lighting to communities around the world so that all life can thrive.
