Next to the Flint River in Flint, Michigan, is a park full of trees with a plaque that commemorates the 25th anniversary of Earth Day.
The sound of the water flowing through that river and the nature around it, helps explain why that plaque is there. Near a red bridge, people photograph the landscape. Nearby, men fish while, standing and looking at the water cascade or they sit and wait for a bite.
