Follow Your Stuff--Who Makes It, Where Does it Come From, How Does it Get to You? by Kevin Sylvester and Michael Hlinka covers a lot of ground. It addresses the whole chain of materials and people required from beginning to end for manufacturing a diverse array of products from t-shirts to medicines. The giant, complex, global economy is clearly explained. As the book states, it's never too early to think about the people in the sequence that produced whatever item you are buying.
