Animal Powered Vehicles
Horse and carriage are just one type of animal propelled vehicle. Once a common form of transportation, they became far less common as cities grew and automobiles took their place. In dense cities, the waste produced by large numbers of transportation animals was a significant health problem. Oftentimes the food is produced for them using diesel powered tractors, and thus there is some environmental impact as a result of their use.

Famous quotes containing the words animal and/or vehicles:
“Afflicted with existence, each man endures like an animal the consequences which proceed from it. Thus, in a world where everything is detestable, hatred becomes huger than the world and, having transcended its object, cancels itself out.”
—E.M. Cioran (b. 1911)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
