Modern Ramifications
Agriculture, deforestation and other land use account for roughly 20 percent of all GHG emissions
More than all of the world’s cars, planes, and trains combined.
three times greater than emissions from the global building sector, and equal to all industrial emissions.
Sector with the second highest rate of emissions
5
Deforestation
Agriculture is the direct driver of roughly 80 percent of tropical deforestation
>50,000 acres of forests are cleared by farmers and loggers per day worldwide,
Cattle ranching, animal agriculture, and logging are the leading causes
Around 6.7 million acres of tropical forests are bulldozed or burned for cattle production each year.
Deforestation in the tropics alone accounts for approximately 15 percent of global greenhouse gas emissions annually.
6
Multiple Choice
Which of these is not a major cause of deforestation
Palm oil
Soy plantations
Livestock
Cranberry Bogs
7
Emissions
U.S. agriculture emitted an estimated 698 million metric tons of carbon-dioxide equivalent in 2018
cattle, sheep and goats—accounts for about 40% of agricultural production emissions in the past 20 years.
irrigated rice fields account for about 11 percent of emissions
Dominant sources of agricultural greenhouse gases (GHGs) include carbon dioxide (CO2) from tropical deforestation, methane (CH4) from livestock and rice production, and nitrous oxide (N2O) from fertilizing or burning croplands
8
Multiple Choice
Which of these are not large producers of methane in agriculture?
Rice
