A project idea I've toyed with is "Where does X come from?", which would show someone, to some approximation, where the things they buy and consume originated, and the path they took to get there, and where their waste goes. Mainly this is inspired by my own curiosity, but also desire to better understand the impact my decisions have on the world.
I haven't pursued it due to lack of time and expectation that acquiring and reducing the data would be a monumental effort, but this looks like a good source for "where does [food item] come from", and has some useful-sounding source databases for tracking other items.
Some other resources I'd want to include: water, sewer, trash, electric (at least where the lines are and nearby power generation), and gas.
