Oranges wrapped in plastic

Here are some oranges individually wrapped in plastic. As if you couldn't see for yourself. Grown and shipped from China. Why? Why? Why? It makes no sense to me, as if a little plastic bag is going to offer any protection. I don't know, maybe it's a marketing technique. Some genius thought the extra sparkle from the plastic might catch your eye? Or maybe they are picked green and allowed to ripen in the plastic bag? Somebody tell me!
