"You Know What You Should Do" by artist Jeff Zimmermann.
This mural is located at the Oak Street Beach underpass entryway and covers the length of 260 feet of space . It was partially funded by the United States Environmental Protection Agency in 2011 to "promote environmental awareness" and "beach preservation."
It is a bit on the abstract side with a hand holding a piece of popcorn in the air as an example of not littering. Images of "Uncle Sam," a Chicago-Style Hot Dog, and Bird Wings around and individual's face are just some of the images utilized in this mural.
FYI-Apparently feeding seagulls at the beach allows flocks to be attracted to the beach and then their fecal matter contaminates the beach water causing it to be unsafe for people to swim.
While good intentions-I am not sure most people would get that message....
Here is what the Chicago Park District stated:
"In 2011, a mural was created by Jeff Zimmermann entitled "You Know What You Should Do" located along a wall running parallel to the Lakefront Trail and is the access point to the Oak Street Beach underpass. The mural, measuring about 260 feet in length and 9 feet tall at the very center, helps raise awareness of beach health and water quality issues. Its message reminds the public to help keep the beaches clean by not littering or feeding wildlife. The project was funded through a grant from the Great Lakes Restoration Initiative through the United States Environmental Protection Agency. Studies have shown that seagull fecal matter could be a contributing cause of swim bans. Feeding the birds and littering attracts the seagulls to the beach."
