3. Shellfish
Maybe you’ve already reduced your red meat consumption and replaced it with lighter seafood fare, like shrimp and lobster. Kudos to you – especially if you’ve lost unwanted weight! But take note shellfish still levies a significant toll on the planet. Every pound of shellfish puts 24 pounds of CO2 into the atmosphere.
4. Pork
The internet may love bacon, but does Mother Nature? Like it or not, pork does put a strain on the environment, albeit small. At 17 pounds of CO2 per pound of meat, a pan of bacon is not quite as hard on the planet as it is on your waistline.
