Indoor cows obviously require more supervision than outdoor cows. That’s just common sense.

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.
