I hope Lloyd checks and double-checks his carbon emissions figures for his book.
Figuring in high-atmosphere climate forcings, a flight from NY to London is about 1.5 tons equivalent. And, where's the evidence that the average footprint of animal products in one's diet is 2 tons? Finally, because of the range of farming techniques and different landscapes, putting a solid figure on the footprint of, say, a pound of beef will be a challenge--and, not even considering that some operations can use livestock to sequester carbon in soil. I think Lloyd may tend to downplay flight emissions and overestimate animal-product consumption, perhaps a hidden bias of his.
I was trying to visualise tonnes of animal manure for an upcoming article. I was really struggling with the large numbers (hundreds of thousands of tonnes) so I needed something that was familiar and weighed many tonnes. In the end, I used concrete mixers.
