I watched a 3-part series regarding The Big Bag Debate: Paper vs. Plastic and would like to share the videos with you. I found this series intriguing as Carrier Bag Shop CEO Sujan Shah discusses a number of issues relating to carrier bags and the environment. He used the brown paper bag with twisted handles and the plastic vest style carrier bag as his subject matters. He reveal in terms the root and raw material, production cycle, packaging (for the bag itself), transportation involved and the afterlife of the bag (reusability and recyclability.) This series is an informative and resourceful tool.
