IB ESS SL 5.2.10 Diet trophic level and sustainability Question Bank

footprint for a meat eater is likely to be much larger than for a vegetarian; production of meat requires a greater energy input than growing crops; (meat eater is) eating at a higher trophic level; means land is required to create feed for livestock and for raising livestock; transport of meat for processing will increase the footprint size; diet based on imported goods will lead to a bigger footprint / local goods will lead to a smaller footprint;
more fossil fuel consumed in process of transportation; increase in material consumption for packaging; greater (food) consumption will mean a bigger footprint; more natural resources (land, fossil fuel, irrigation) required for meeting increased demand;
