"You’ve heard that carpooling and buying more efficient vehicles is good for the planet. Perhaps you’ve even participated in Bike to Work Day or dreamed of getting an electric car or hybrid to do your part.
But did you know that agriculture — specifically the breeding and raising of animals for food — contributes more to global warming than transportation?
And, of course, industrial-scale agriculture and especially animal-based agriculture is one of the planet’s heaviest users of transportation as well. Furthermore, animal agriculture is the leading cause of species extinction and ocean dead zones.
It makes sense then that the Intergovernmental Panel on Climate Change (IPCC) suggests reducing consumption of meat, milk, cheese, and butter as a critical way to reduce your carbon footprint."
