I’m not against these ideas but you do have to zoom out a bit to fully realize the impact of each alternative. It’s not as simple as replacing a “bad” one with a “good” one, because there are side effects.
(I haven’t added up the total impacts of every option either; this is just something to consider.)
For example, glass is much heavier than the plastic used for bottles. If you have trucks/etc. hauling millions of bottles around the world, it will take more energy to move glass bottles. Glass is also fragile so it’s possible there is more shipping material or more random losses affecting cost. So then the problem is not just how to replace plastic bottles with glass but how to offset the added environmental cost of transporting glass.
