Summary of Emissions of Agriculture and Livestock
Global Impact
Agriculture contributes approximately 25% of all greenhouse gas (GHG) emissions:
- 80% of agricultural emissions come from animal agriculture products (meat, milk, eggs)
- Livestock production accounts for 70% of all agricultural land and 30% of the land surface
(Source: Mulvaney 2020, p. 218 f.)
Key Statistics from “The Game Changers”
-
Egg, fish, meat, and dairy farming require 80% of farmland but only provide 18% of the world’s calories (Source: Poore et al, Science 360(6392)987-92) (#visualization-idea)
- In the United States, farm animals produce 50 times more waste than the US population
- Up to 1/3 of animal products is wasted

Statistic from @Kqed
- Excluding human biomass, 94% of mammal biomass on Earth is livestock

Visualizing the ratio of wild mammals to domesticated mammals
This visual was inspired by a statistic I couldn't believe at first: The vast majority of mammals that live around humans is domesticated and used for human consumption. Only a small fraction of all the mammals around humans lives a "free" or "wild" life. Disclaimer for the graphic: I know...
