What’s better for the environment, large factory farms shipping their products across the country in petroleum-powered transport, or small local farms distributing locally?
The counterintuitive answer seems to be large factory farms. [I do not have a citation for this at this time; it is something I remember, because it surprised me. Economies of scale, I guess, like shipping $0.05 tchotckes from China on mega-container ships is still profitable.]
So, I would like to see a study on mass-produced large-batch consumer products vs small-batch items.
NOTE: I do see that yours is not a knee-jerk response, and acknowledges that they may be the same; although I suspect it may actually (and sadly) be reversed.
