What's with all the trash along the I-5 corridor between Olympia and Seattle? Where does it all come from? I'm guessing the soda bottles and fast food bags come from the cars and trucks, chucked out the window by uncaring people that have no respect for their surroundings and others. Some of it looks like the plastic wrap used to wrap the cargo on big semi-trailers. Does anyone know for sure?

I do know that the state of Washington pays over $2 million annually to dispose of the trash picked up along the state highways by volunteers and prison inmates. Check out Department of Transportation's website for more details. I'm assuming a significant percent of the litter is disposable packaging designed to contain our convenience food and then be thrown away without a second thought. Why are we using state resources to pick up trash that is associated with products that are unnecessary to begin with and even unhealthy?
