After class, I go around the room where I teach and pick up and discard bottles and cans. One thing I've noticed recently is that people often leave plastic bottles of water laying around the room, half full. This has always bothered me, because the night watchman, an older gentleman, has to then go around and pick up the bottles. But this has gotten me thinking.
At my university, a 12 fluid ounce bottle of water costs $1.50. A gallon has 160 ounces in it, so there are roughly thirteen 12 fluid ounce bottles of water in the gallon. That means that people are paying $19.50 per gallon of water by buying that bottle of water, which they leave on the ground.
People complain that gasoline costs will hit $4 a gallon this summer. However, they have no problem leaving half a bottle of spring water that costs $19.50 a gallon on the floor of my classroom. Of course, you're not really paying 19.50 for the water - you get the plastic bottle, itself made of petroleum.
When I brought this up this evening to the night watchman, she shook his head. "I guess these kids have some rich parents paying their way through..."
people have come here searching for the cause of and solution to all of life's problems.
