Untreated animal excreta
- Uncollected animal droppings
- Pollution by animal dung
Nature
The excrement of domestic animals in cities and in the countryside is increasingly posing pollution problems.
Incidence
In industrialized countries, the problem of horse dung in cities prior to the advent of motorized transport has been replaced by dog turds. Animal excrement in the streets and other public places and in domestic situations continues to be a problem in many less-developed countries.
