Now, let's talk about the other components:
the ink (petrochemicals, for the most part)
the production, transportation, and containers for the ink
the runoff into our biosphere from the ink production
the transportation of the paper to the printing facility
the binding (glue)
the transportation of the catalogs to the stores
the plastic wrap and other packaging for the catalogs
the labor put into it (perhaps those people could be paid to rest instead? probably better for everyone all-around)
Did I miss anything?
How many dead, displaced, or injured animals do you think that is per catalog? How many humans harmed by exposure to manufactured poison? How many gallons of diesel extracted, transported, refined, transported again, and burned? How many dozen pieces of trucks, trains, and container ships mined, produced, and worn down? Is it still better than viewing the same catalogs online on an already existing computer screen?
Every single artefact produced by our system has a similar footprint. It's not just money cost. And I think it's worth considering.
