Margaret Teich of G Spotting just did a piece on who petroleum is almost in every product we buy.

You see the life cycle of products and whether that product is really sustainable depends on a host of factors. Some of them are: what type of energy was generated to create the product, what core materials are used to package the product, was the product made locally or shipped via vessel, truck, train or car, and more.

Think about that when you watch this clip!
