I think you have to hike through largely untouched forests to a very remote lake to find sharp glass shards scattered across the little beach to realize that glass maybe isn’t the most environmentally-sound magic-solution that some people would like to think. It can be just as (and much worse) strong at causing ecological catastrophies that are incredibly expensive to clean up.
The symptoms are: littered streets, nature.
The causes: fuckfaced fuckwads for people. In all areas of society.
