I must admit it, I love hamburgers, but these facts make me ponder more what I eat:

• More than 20% of the global greenhouse gases emissions (13.6 gigatons per year) are a direct result of food production, 61% of that can be traced to three main factors related to meat production:
  • Destruction of carbon-reducing forests and habitats to make way for pasture land
  • Pasture grown with carbon-producing fertilizers
  • Cattle and sheep producing large amounts of methane as a byproduct of the digestive process 💨
• Methane is one of the most potent greenhouse gases (80 times stronger than CO₂)
• Beef production generates 30 pounds of CO₂ for every pound of meat

See this food carbon footprint comparison chart from OurWorldInData.org:

A single cheeseburger has the same climate impact as driving a typical car more than 20km/10 miles
