I think the point is that we just never know. What I view as trash may be a life saver for another. I remember one time when I was at the Minnesota State Fair and a young woman walked by, dug into a trash can, and pulled out part of a sandwich or something that she found and began to eat it. I wanted to offer to buy her something fresh but it all happened so fast she was there and gone in a flash.
I don't know but I wonder of used defective DVDs/CDs can be recycled? I remember playing with broken toys when I was a child some 50 years ago or so. We turned them into new toys sometimes. My cribbage board is missing most of the colored pins but it doesn't stop us from using it to play the game. We use toothpicks, stick matches, or anything else we can find to work as a pin. I've even seen toddlers play with dolls that are missing limbs. They don't care. They are still able to play using their imaginations just the same.
