The article highlights the significant role of soybeans as the world's largest source of protein for livestock feed, with global production doubling since 2000. The majority of soybean production is located in South America, particularly in the Amazon rainforest, with Brazil being the dominant exporter. The demand for soybeans is driven by the growing meat consumption, especially in China, where soybean meal is a crucial ingredient in pig feed. The article also discusses the potential impact of plant-based food consumption and population growth on soybean demand. It notes that alternative protein sources to soybean meal are being explored, such as wheat, and that Europe may decrease its soybean use due to declining pork consumption and new legislation allowing the use of animal by-products for animal feed. The article also mentions the potential of synthetic amino acids to reduce soybean use in livestock feed.
