Noting that he is an MIT graduate, Wolf said he calculates that if every Pennsylvanian picked up one piece of trash a week for a year, it would come to seven thousand tons of garbage.

“That’s how powerful individual action is, and that’s why what we’re doing today is really important,” he said.  “It’s not just symbolic. It’s not just an effort to get you to come out and take pictures.  It’s actually important.”
