Chicago area groups geared up for Earth Day

The Grant Park Conservancy and Advisory council, with help from volunteers from Exelon Corporation, did some spring maintenance around the park.

Participants mulched and weeded approximately 2, 000 trees they've planted over the past two years.

In another part of town, Brookfield Zoo threw its 'Party for the Planet.' The pre-Earth Day bash featured green-themed games for kids, music and, of course, lots of animals on display.
