Litter Picking Dog

Litter consists of waste products such as containers, papers, and wrappers which have been disposed of without consent. Litter can also be used as a verb. To litter means to throw litter onto the ground as opposed to disposing it properly.
Throughout human history, people have disposed of unwanted materials onto streets, countrysides and remote places, unpunished. Prior to reforms within cities in the mid to late 1800s, sanitation was not a priority on governments' lists of things to do. Waste was disposed of by the roadside or in small local dumps. It was unsanitary for local inhabitants and the growing piles of waste led to the spread of disease. The only known pre-modern exception, however, was the Arab Empire, especially in Cordoba, al-Andalus, which had facilities for litter collection.
