Over the past twelve years, Richard Lang and Judith Selby Lang have collected several tons of plastic debris on a small stretch of beach near their northern California home. The pieces of plastic are cleaned, categorized, and sorted, before the couple goes to work transforming the garbage into beautiful pieces of art. This short doc profiles the couple and their creative output and the problem of plastic pollution generally. It's a good one.
