The meat industry is facing some major sustainability problems. Animal livestock uses a disproportionally large amount of land. Of the 51 million km2 of agricultural land, 77% is used for livestock and feeding livestock. Despite this, only 17% of global caloric consumption comes from animals, with plant-based foods supplying 83% of global caloric intake. Only 33% of global protein intake comes from meat and dairy.
The world’s population is expected to reach 10 billion by 2050. Feeding this many people will require an increase in global food production of 70%. However, major crop yields have been plateauing over the last decades. Over the last 50 years, selective breeding has pushed animals to their biological limits.
