Harvard Response: "The panel declared “considerations of environmental impact” out of the scope of their recommendations. This is a missed opportunity because climate change and environmental degradation have serious effects on human health, and thus is important to consider when making recommendations on diet, even if this is addressed separately from direct effects on individual health."

My response: should we apply this to other topics as well? Pimp the efficiency of renewables compared with carbon-based? Up the effectivity of hydrogen-based energy distribution? Lift the results of a study promoting working from home?

Two words come to mind: Occam's razor.
