Here is my idea for all big cities with a problem of discarded fridges on the street. Jut make pots out of them and plant anything inside. In my project last year I’ve planted sunflowers and tomatoes in a fridge I’ve found outside on my road. I’ve even managed to get free soil from FREECYCLE.ORG as it turned out someone nearby was digging a basement and had a lot of nice soil for free. Most people think that I’m crazy and I simply know that since I was about 3 years old. 🤣
