Dung

A documentary investigating the historical, cultural, medical, scientific and evolutionary importance of excrement, hosted by marine biologist Monty Halls.

During the rainy season in Africa, a herd of buffalo can create thousands of pounds of waste in a day, which would be an environmental disaster if not for the dung beetle. These extraordinary insects depend on waste to survive. They eat it, attract mates with it, and raise families in it. Although dung beetles are critical to the ecosystem, they don't have it easy. Every day, they must avoid being trampled, evade predators like bullfrogs, honey badgers, and rock monitor lizards, and rival dung beetle families desperate for the same fecal prize.

Explore a surprisingly wild and little-known part of America's heartland, and witness the efforts to restore it.
In northern Montana is a massive wildlife sanctuary on track to become one of the largest, protected ecosystems in the United States: the American Prairie Reserve. Here, scientists and ranchers are working in partnership to restore these grasslands to their natural state. To do that, they must bring back the animals, starting with the keystone species: Bison. Enter America's heartland and witness surprising landscapes and never-before-filmed animal behavior.

This book covers the basics of animal manure, or animal dung, and highlights its applications in agriculture and biotechnology. The reader is given a comprehensive overview of the different types of animal manure. Although animal manure can cause environmental problems, e.g., when slurry pollutes rivers or burnt dung pollutes air, the book emphasizes the fact that animal dung is by no means a waste product. Animal manure is a valuable organic fertilizer that has a positive impact on soil conditions and helps save on chemical fertilizers. It is also a source of energy and can be either be used as fuel or converted into biogas through methanization. Old-age practices such as the use of dried dung as insulating material, or burnt dung as mosquito repellent are also taken up.
