Cow Exhaust

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. Transportation exhaust is responsible for 13% of all greenhouse gas emissions. Try making some vegan chili once in a while. You'll be happier and so will the earth.
