Factoring in both direct and indirect factors, the production of livestock is responsible for
producing approximately 15% of all greenhouse gas emissions across the globe, which has an impact on
global climate change. According to one study, producing 1 kg of beef in the US emits 14.8 kg of CO2
equivalents into the environment. In comparison, 1 gallon of gasoline emits 2.4 kg of CO2 equivalents
when burned. The average midsized car can go 25.8 miles for each gallon of gas. How many miles could
a car drive to produce the same amount of CO2 as is emitted when a quarter-pound hamburger is
produced?
