Livestock Emissions: The Big Five
Cows (1/5)
Population worldwide: 1.3 billion
A single cow produces 250 to 500 liters of methane every day. The warming effect of methane is 25 times more powerful than that of carbon dioxide. Methane from all cattle worldwide has an enormous impact on global warming.
Moreover, a single dairy cow produces 20 to 40 times more excrement than a person. Handling this large amount of manure is a problem for many farmers.

Livestock Emissions: The Big Five
Sheep (2/5)
Population worldwide: Over 1 billion
Sheep vent about 30 liters of methane per day. In New Zealand, where sheep outnumber the people by about 12 to 1, methane emissions from sheep are responsible for almost half of the country’s combined CO2-equivalent greenhouse gas emissions. Scientists are working on a vaccine that might reduce methane emissions in sheep by about 20 percent.

Goats (3/5)
Population worldwide: 800 million
Goats are able to survive on almost anything, even plants toxic to cattle and sheep. Their digestive systems can break down nearly any organic substance. The process, however, produces significant amounts of methane.
Scientists estimate that over a third of all cereal production is needed to feed livestock. Intensive animal farming will also spur deforestation and loss of biodiversity. Goats, however, are seldom bred in large farms and consume less grain. And given their unpicky eating habits, they are even deployed to clear undergrowth and prevent wildfires.

Pigs (4/5)
Population worldwide: 1 billion
The biggest threat comes from pig manure that is dispersed on fields and pollutes groundwater, rivers, and lakes. A 90-kilogram pig excretes around 100 kg of nitrogen and about 20 kg of phosphorous per year. Both substances act as fertilizers and can trigger overproduction of algae and disrupt entire aquatic biosystems. (Photo: Reuters)

Chickens (5/5)
Population worldwide: 17 billion
Animal welfare groups often target the chicken industry for the methods under which chickens are raised, transported, and slaughtered. UN experts also target poultry farming in Asia as a source for bird flu pandemics. Certains virus strains can also infect humans, like the H5N1-strain that had killed 206 people as of November 2007.
