Now let’s be clear. I’m not against reusable bags, in fact I am all for them.
That being said, think it through. Just how many of those do you need before they start to be wasteful just like the disposable bags they’re replacing? Every craft fair, grocery store, conference and gala event seems to give you one these days, and most of them are just crappy enough, small enough, or an odd enough size and shape that they really aren’t that usable in the first place, much less reusable.
So by all means if you use a bag, use a reusable one. But sometimes, do you really need a bag at all?
