Zoo officials have decided to hold a daytime Wild Wonderland instead of the usual nighttime event. On hand will be Clydesdale horses, reindeer and craft workshops where children can make eco-friendly tree ornaments.
By keeping the lights off, zoo officials hope to reduce the zoo's carbon footprint, which is a measure of greenhouse gases emitted by human activity.
The zoo says moving the event to the daytime will reduce its carbon footprint by an amount equal to the annual emissions of a three-person household.
Winter Wonderland will be open beginning December 6 from 11:30 a.m. to 3:30 p.m.
