From the UN


When emissions from land use and land use change are included, the livestock sector accounts for 9 per cent of CO2 deriving from human-related activities, but produces a much larger share of even more harmful greenhouse gases. It generates 65 per cent of human-related nitrous oxide, which has 296 times the Global Warming Potential (GWP) of CO2. Most of this comes from manure.

And it accounts for respectively 37 per cent of all human-induced methane (23 times as warming as CO2), which is largely produced by the digestive system of ruminants, and 64 per cent of ammonia, which contributes significantly to acid rain.

Livestock now use 30 per cent of the earth's entire land surface, mostly permanent pasture but also including 33 per cent of the global arable land used to producing feed for livestock, the report notes........

The biggest question I have is about the 30 percent of the entire earths land surface? I think they mean usable land.

That's what they say. 30 percent of land surface, which includes pasture and includes using 33 percent of the world's arable land to grow feed.

That's all livestock.

Ammonia solved in water acts like a base, not an acid.

I thought is sounded wrong with acid rain remembering something about base, so I did a quick browse in Wikipedia. I'm on a time restraint right now. If someone knows, please explain "which contributes significantly to acid rain."

Man... They really are explaining themselves badly, or purposefully wrong.....

Ammonia is a base (ph 11 to 12). The ammonia ion actually decreases the acidity of rain. Looking at this map makes it look as if the higher ph is linked to the higher ammonia.

Interesting. But I am not the scientist.
