Green house gases: plants vs meat

Updated: Apr 16, 2019

Considering that worldwide agriculture produces 25-33% of total greenhouse gases (IPCC, 2014), there has never been a better time to think about what difference you can make with what you are popping in your gob. Not all foods have an equal impact on greenhouse gases production per gram of protein produced, as the quote in the post shows. ⠀ ⠀ Through various reviews it has been consistently found that ‘plant-based foods often have the lowest GHG emissions per kilocalorie of food produced’ (Clark, Hill and Tilman, 2018). So munching more legumes (lentils, chickpeas, beans, split peas etc) instead of beef, will benefit the planet, your health (due to the high fibre content - (Reynolds etc al., 2019)) and the your wallet. Triple win! ⠀ ⠀ How would you change to a more plant based source of protein? ⠀ ⠀ Evidence:⠀ Clark, M., Hill, J. and Tilman, D., 2018. The Diet, Health, and Environment Trilemma.
