A greener source of polyester - cork trees

On the scale of earth-friendly materials, you'd be hard pressed to find two that are farther apart than polyester (not at all) and cork (very). In an unexpected twist, however, scientists are figuring out how to extract a natural, waterproof, antibacterial version of the first material from the latter.
