How to live with our Earth

So the other day I am taking the car to get serviced and I am behind a mini van, suddenly something white comes flying at my windshield and it startled me. Turned out it was just a wad of tissues or napkins. But it starteled the heck out of me. Next came a cigarette butt, then finally a plastic soda bottle. Realizing that these people were using the highway as their personal trash canI decided I was going to get thier license plate number and report them. I was successfully able to get it but I was a bit disappointed when I called the local police department. When I talked to the dispatcher I said I wanted to report someone throwing trashout thier car window not into the trash can. I could hear her muffling laughter and it started to really anger me. Their are signs up and down the highway that say 300 dollar fine for littering. Honestly, normally I would not take the trouble to call but when I saw the plastic bottle come out it really ticked me off. I really wish that if all of us just took a few simple measures we could improve our planet rather then destroy it. I'm assuming these people have kids since they were in a mini van and I thought what a bad example they are sending to thier family...
