Here are a few relevant facts from the documentary:
- Animal agriculture is responsible for 18 percent of greenhouse gas emissions, more than the combined exhaust from all transportation.
- Livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51% of all worldwide greenhouse gas emissions.
- Methane is 25-100 times more destructive than CO2 on a 20 year time frame.
- Methane has a global warming potential 86 times that of CO2 on a 20 year time frame.
- Livestock is responsible for 65% of all human-related emissions of nitrous oxide – a greenhouse gas with 296 times the global warming potential of carbon dioxide, and which stays in the atmosphere for 150 years.
- Emissions for agriculture projected to increase 80% by 2050.
- Even without fossil fuels, we will exceed our 565 gigatonnes CO2e limit by 2030, all from raising animals.
