The problem isn’t just plastic, it’s the long supply chains. Let’s take juice bottles, you stop using plastic, what do you use? Single use glass isn’t good either, it takes a lot of energy to recycle it, way more than plastic (not that we are actually able to recycle plastic), metal cans are probably a bit better but they also have their energy costs. Reusable glass is the best, but it still has to be moved by heavy truck back and forth from the bottling plant.
