Information:
The League of Women Voters of Sioux City and Northwest Iowa Group of Sierra Club are cohosting a presentation on light pollution on April 30, 2023, 2:00pm at the Sioux City Public
Museum, 607 4th Street, Sioux City. There is not an admission fee.
David Hoferer, local Sierra Club member and Briar Cliff University biology professor, will lead a
discussion after the presentation on this growing phenomenon, and explore with us what steps
individuals can take to improve the impact on our natural surroundings.
Artificial lighting has been shown to have many consequences - both positive and negative- for
humans and wildlife. Light pollution, or artificial light at night, is the excessive or poor use of
artificial outdoor light, and it disrupts the natural patterns of wildlife, contributes to the increase
in carbon dioxide (CO2) in the atmosphere, disrupts human sleep, and obscures the stars in the
night sky.
The event will be live streamed on LWV Facebook page, “League of Women Voters of Sioux
City.”
