Just an FYI, shipping means “the process of transporting packages and mail from one location to another” not literally transporting goods internationally on a ship.

Everything is a compromise. We could bring back paper in a larger scale, but then more land would have to be dedicated to working forests which are sustainable but aren’t ecologically friendly. We could bring back glass in a larger scale, but that would make shipments much heavier thus increasing the emissions required to ship it.
