Energy use, blue water footprint, and greenhouse gas emissions for current food consumption patterns and dietary recommendations in the US
...This study finds that shifting from the current US diet to dietary Scenario 1 [eat less] decreases energy use, blue water footprint, and GHG emissions by around 9 %, while shifting to dietary Scenario 2 increases energy use by 43 %, blue water footprint by 16 %, and GHG emissions by 11 %. Shifting to dietary Scenario 3, which accounts for both reduced Caloric intake and a shift to the USDA recommended food mix, increases energy use by 38 %, blue water footprint by 10 %, and GHG emissions by 6 %. These perhaps counterintuitive results are primarily due to USDA recommendations for greater Caloric intake of fruits, vegetables, dairy, and fish/seafood, which have relatively high resource use and emissions per Calorie.
I like this. It makes me think I should be supporting the plant based lacto-ovo-pesco vegetarian diet since a little bit warmer climate is better for the environment than a new ice age (that we may be perilously close to).
