Speaking of deforestation: > Globally, 77% of soya is produced for animal feed, 19.2% for direct human consumption and 3.8% for industry (biodiesel, lubricants, etc.). https://www.deforestationimportee.ecologie.gouv.fr/en/affect... Poultry protein efficiency is 21% and beef 3% > We find that reallocating the agricultural land used for beef feed to poultry feed production can meet the caloric and protein demands of ≈120 and ≈140 million additional people consuming the mean American diet, respectively, roughly 40% of current US population. https://iopscience.iop.org/article/10.1088/1748-9326/11/10/1... Edit: Note the soy usage vary around regions. The first link is from a French gov page, after the previous citation it gives the world repartition: > In animal feed, the largest consumer of soybeans is chicken (37% of world production), followed by pork (20.2%), aquaculture products (5.6%), dairy products (1.4%) and beef (0.5%). Which is quite different than the French reparation : > flesh and egg poultry account for 44% of total [imported] soy, then diary/mixed cows (36%) then flesh cow (8%) and pigs (6%) (fr) https://chaire-bea.vetagro-sup.fr/en-france-les-animaux-dele... Soy protein are 97.9% as digestible as beef > protein qualify can be scored in terms of its Protein Digestibility-Corrected Amino Acid Score (PDCAAS). Soy achieves a PDCAAS of 0.92, comparable to beef at 0.94. https://ourworldindata.org/land-use-diets The DIAAS is sensibly worse (soy 0.898 - beef 1.116) but still far from the beef protein efficiency cited above (3%) https://en.wikipedia.org/wiki/Digestible_Indispensable_Amino... | ||
