Augalinai baltymai yra daug pigesni. Iš vieno hektaro žemės galima gauti 280 kg [[jautiena|jautienos]] arba 11200 kg [[soja|sojos]] pupelių. Tokiam pat kiekiui išgauti pupelių reikėtų tik 300 litrų vandens. Išgauti 1 kg baltymų iš pramoniniu būdu gaminamos mėsos reikia 50000 litrų vandens. JAV maistui auginami gyvuliai sunaudoja 50 % vandens resursų, 90 % sojos, 80 % kukurūzų, ir 70 % grūdų derliaus.<ref>Vesterby, Marlow and Krupa, Kenneth S. 2001 Major Uses of Land in the United States, 1997 Statistical Bulletin No. (SB973) September 2001 http://www.ers.usda.gov/publications/sb973/sb973.pdf</ref>
