The mailbox ritual goes something like this—open the box, and out spills a slew of envelopes and catalogs. Bills get separated from coupon mailers. Holiday cards and invitations get dug out of a tangle of credit-card offers and other solicitations.
No one loves it, but everyone gets junk mail. It’s a relentless tide of paper that comes to your doorstep unbidden and often ends up in a garbage can moments after entering the house.
The production, distribution, and disposal of all that junk mail creates more than 51 million metric tons of greenhouses gases annually, the emissions equivalent of more than 9.3 million cars. That’s more than all the cars registered in Los Angeles and New York City combined.
Besides, the trees are more worth keeping around than the flood of marketing materials. Yale researchers estimate that since the dawn of humanity we have cut down half the trees on the planet, and there are about 3 trillion left—which leaves us with about 400 trees a person.
