In this video, we look at the environmental impact of products and how we determine this using a life-cycle assessment. We then carry out simple life-cycle assessments for plastic and paper shopping bags.

This video is based on the AQA spec. If you are following a different exam board then you should check your specification. The Amazon link above is an affiliate link.
