This is totally awesome and very practical. I absolutely HATE to waste food. My grandma grew up on a farm and her favorite saying was, “We ate everything on the pig but the oink.” haha People need to learn to maximize usage of all goods and materials. And, minimize waste. We all should focus more on preservation and recycling as well. Global sustainability and practicalities. It may seem “obnoxious” to go to so much trouble over leftover lettuce but it’s really quite ingenious. These are the types of activities we should be integrating into our public school curriculum. If nothing, at least students will have learned a cool agricultural science lesson. Bottom line, so many people across the globe are starving and our ecosystem is collapsing. Learn to truly appreciate what you have and also, appreciate the bigger picture.
