History Channel's "Life after People: The Series" chronicles what happens to our planet and more specifically its landmarks, buildings and other human made objects after people are gone forever.
In one specific episode known as "Life After People the Series: Outbreak" The program explains what would happen to Chicago, Atlanta and London after people are gone for segments of time from 1 day after people are gone to up to 5000 years+ into the future.
Highlighted in this episode is our beloved Wrigley Field along with the Chicago skyline and what will happen to the most notable icons of humanity long after we are gone.
This program is perfect for family viewing and answers alot of questions that children may have about the world in which we live.

I highly recommend checking out this program and this series for that matter, but most specifically this episode since it does focus attention on Chicago and Wrigley Field.
