Now I don't feel so left out with rentals being damaged. When DVD first came along I said "no way, it'll never work for rentals" then I rented a couple and said "ok, it works, bring on the crow". Well, it was like that, at first. When people were careful with DVDs like people used to be careful with CDs. Now a DVD is scratched to hell after 1 or 2 rentals and even though you can look at them as you check out at the video store, you just never know what little scratch is going to ruin the night.
So yeah, I've quit renting as well. Only time I'll rent is a new release if I can find a pristine disc. Otherwise it's too much trouble. Actually I have rented VHS again since I've run into damaged rental discs.
I was thinking about this a bit today. More I thought about it, the less the environmental side stuck out. AOL CDs, there's the obvious comparison. They are junkmail. It's trash. America Online is mailing you trash. Of course it's wasteful.
Disposable DVD you're getting use from. So it's not absolute trash to start with. That really is something to consider, usefulness/waste ratio. Plastic bags - they make up for a lot more landfill space than disposable DVD ever will (even if everyone rented and tossed a DVD every night BlockBuster would still put it in a plastic bag so it'd never catch up). Similar use/waste ratio since most people toss them soon as they get home....but even among my friends who are very ecofriendly few take their own canvas bag to the grocery store. They recycle the paper or plastic they get. It's not perfect, but it works.
Personally I try to save mine and give them to Goodwill. The store here uses used bags.
But back to the point, yeah there's more landfill space taken up in the end. At the end of movie night a plastic bag, two plastic pop bottles, a plastic Doritos bag, a cardboard popcorn bucket, a pizza box and a DVD disc will go in the trash. Or get recycled. Still goes back to the end user whether it goes in the trash or the recycle bin, and by percentage it's a tiny effect either way.
Now talk Disney into putting a 5 second "Please Recycle" message at the beginning with the FBI warning and it can end up being a net benefit. All about approach and application.
