Three items

Refridgerator: Fridges are big, hefty pieces of engineering with lots of different materials on them. Among them, copper, which has a huge mining industry behind it.

Football: I want to know how my favorite past time winds up in my hands. As a personal question, I want to know whether my "pigskin" is actually made of pig.

Fiberglass insulation: The stuff that keeps my house warm is also the bane of my existence. Where does this awful material come from, and how does such a facility that produces it have an impact on the environment?
