What is International Dark-Sky Week?

Today, April 5th, starts off International Dark-Sky Week, held by the International Dark-Sky Association. But what does this mean?

In 2003, a woman named Jennifer Barlow coined the event in efforts to raise awareness about light pollution. She says she “want[s] people to be able to see the wonder of the night sky without the effects of light pollution. The universe is our view into our past and our vision into the future. I want to help preserve its wonder.”

Although the effects are seemingly harmless, the consequences of light pollution are far-reaching and harmful for all species. Any artificial light that is not needed is a pollutant, which adds up extremely quickly across the entire world. Light pollution disrupts wildlife, contributes to climate change, and blocks our view of the universe. It has the potential to blockade humans from the universe we live in and we are slowly walking towards it.

So how can we celebrate International Dark-Sky Week? First, we must stay alert and aware of our light usage. Inefficient lighting creates glare and wastes massive amounts of energy (and money). Inspecting any poorly installed or unnecessary light can help mitigate such effects. The International Dark-Sky Association (IDA) also holds a seal of approval for outdoor lighting that minimizes glare, light trespass, and skyglow. Use these products to replace old lights! Finally, discussing light pollution with friends, family, and your community is the biggest support. Taking lighting and electricity for granted can only go so far before the earth changes forever. To learn more, the IDA suggests becoming a “citizen scientist” and participating in their Globe at Night campaign.
