I posted a similar message in off-topic and was mocked for being naive. I wanted to mention that my UPS store happily takes cardboard boxes and re-uses them, which I have to think is better for the environment than recycling. I spoke with a UPS employee at my store and asked her whether they just recycle the boxes that we bring in, or whether they actually re-use them. She confirmed that they do in fact re-use them and they are happy to have them. These are boxes that I bring in shortly after receiving them in the mail, so they are not dirty, wet, etc. I guess that now that Amazon and other sellers allow people to return items without boxes at the store, they are in constant need of boxes to ship items. I encourage you to ask your local store about their policy. It feels great to see these nearly new boxes get re-used rather than processed in the recycling. (Before you flame me, I know that obviously would be better to not have so much shipped to the house.)
