It's getting cold. Time to break out the fleece. Warm and light, it even comes in a nice shade of green: a lot of the material used to make fleece comes from recycled plastic bottles -- better in your sweater than in a landfill.
Green that is, until you run it through the washing machine. That's when thousands of plastic microfibers get flushed into the sewer system and on to some stream, lake, river and ocean.
