I am convinced there is a subspecies of the genus humankind existing in our area. Although I may never have actually spoken to one or seen one, I see evidence of their existence along the roads I walk, run, and bike.
This evidence consists mainly of discarded alcohol containers, usually a cheaper, popular beer; fast food containers; plastic beverage containers, and paper products.
Because of what I would consider a lack of consideration for others, I doubt the members of this subspecies, perhaps more humanoid than human, could read or assimilate the content of this letter. If one were able to interpret their primary means of communication through grunts and gestures, one might be able to ask why they choose to litter our environment. We might be able to take it even further and convince them to all live together in an enclosed area so they could befoul their own living area with the detritus they impose on us. I am open to suggestions.
