I try to use phones and laptops for as long as possible, knowing that alternatives would be more sustainable than plastic. Unfortunately it is not easy to find an equally versatile and durable enough material for phones or computers. In any case, maybe I was too vague... I actually meant that such a use (wrapping two wafers to make easier to take them) seems useless. It's just more senseless plastic... seriously can't you "bother" a little to get the first ones, just to avoid other plastic that in 90% of cases won't be recycled? Maybe we should change the way we think, starting from many small things like this, because the best changes all start from that.
