Environmental Impact of Food Transport

The video discusses the concept of food miles, which measures the distance food travels from production to consumer, and its environmental impact. It highlights the complexity of calculating a product's carbon footprint, emphasizing that food miles alone are insufficient. The video introduces life cycle assessment as a more comprehensive method, considering factors like production, storage, and transportation. Case studies on lamb and apples illustrate the nuances of carbon footprints. Practical tips for consumers include avoiding air-transported food and buying in-season produce. The video concludes with a call to action for informed consumer choices.
