CHICAGO — Communication theorist Marshall McLuhan said, "There are no passengers on Spaceship Earth. We are all Crew."
It is in that spirit that communities across the city gather to celebrate Earth Day and residents can pitch in to make their green spaces a little nicer.
Earth Day is celebrated each year on April 22, but many parks will be commemorating on Saturday with cleanup events, tree plantings, entertainment and other activities.
Here are a few Earth Day events going on in the area:
Humboldt Park, 1440 N. Humboldt Drive, will be celebrating the 20th anniversary of its Earth Day clean-up, which attracts some 500 volunteers each year.
The day's events include:
-- Clean-up from 9 to 11 a.m.
-- Tree planting at 11:30 a.m.
-- Entertainment from 11 a.m. to 1:30 p.m.
-- Earth Day activities from 11 a.m. to 2 p.m.
