For the latest installment of the Wild Neighbors Series, dark skies advocate Cindy Luongo Cassidy will be giving an online presentation on the consequences of artificial lighting on the natural world. Almost every living thing depends on the cycle of light and dark. Yet as the state’s population has boomed, dark skies are becoming increasingly threatened and the ensuing light pollution affects animals, plants and even human health. In addition to giving participants a peek at real darkness, Cassidy will share information about “outdoor lighting practices that let us have the light we need, while saving energy, reducing glare and limiting negative consequences on the environment.” Participants will receive a digital handout with drawings of recommended light fixtures. Register to attend here. Login info will be sent before the event. Thursday, Oct. 1, noon-1 p.m. Wild Neighbors is hosted by Travis County and City of Austin Balcones Canyonlands Preserve partners.
