The two most significant greenhouse gases related to animal agriculture are: *

Methane and carbon dioxide

Methane and nitrous oxide

Methane and water vapor

Carbon dioxide and nitrous oxide

The largest agricultural source of nitrous oxide is *

Manure management

Soil management

Enteric fermentation

Composting manure

The correct ranking of greenhouse gases for global warming potential from smallest to largest is: *

Carbon dioxide < methane < nitrous oxide

Carbon dioxide < nitrous oxide < methane

Methane < carbon dioxide < nitrous oxide

Nitrous oxide < carbon dioxide < methane

Which of the following is the largest source of agricultural methane emissions? *

Enteric fermentation

Manure management

Rice cultivation

Inorganic fertilizer aplication

In the fact sheet "Why Does Climate Change?"? Which of the following was not listed as a anthropogenic/human force on climate ? *

aerosols

greenhouse gases

volcanoes

land use changes

Provide two examples of an agricultural direct greenhouse gas emission and a related indirect emission for each. *

For example: The fuel burned in a tractor during manure application is a direct emission. The greenhouse gases emitted during the manufacture of the tractor is an indirect emission. (Now, you come up with two different examples.)

Place a check next to the items that are examples of adaptation to climate change. Leave blank the items that are examples of greenhouse gas mitigation. *

Covering manure storage/anaerobic digester

Building shade structures in a cattle feedlot

Increasing the size of ventilation fans in a dairy barn

Reducing fertilizer use due to a nutrient management plan

Buying larger planting equipment to finish field work quickly

Enrolling crop land in the Conservation Reserve Program

Required

List four ways farmers/ranchers can reduce greenhouse gas emissions. *

Methane has a carbon dioxide equivalent of 32. What does this mean? *

Humans create 32 times as many pounds of methane as carbon dioxide

It has something to do with the mass of the molecules

A pound of methane is 32 times more effective at trapping atmospheric heat as a pound of carbon dioxide

Methane is 32 times less effective at trapping heat as carbon dioxide

Which type of animal emits the most methane via enteric fermentation? *

ruminants, especially beef and dairy cattle

poultry and birds

pigs

horses
