Animal agriculture has been identified as playing a large role in climate change. I am interested in how much of a difference someone can make through diet changes.
How much is the average North American's greenhouse gas footprint reduced by eating vegetarian? What about vegan?
See this article: The carbon footprint of 5 diets compared - shrinkthatfootprint.com
It suggests that the average person produces 2.5 CO2e a year while a vegetarian only produces 1.7 CO2e a year, and vegans produce 1.5 CO2e a year.
Apparently, 18% of global carbon emissions come from livestock
