You might not be able to stomach soybeans for breakfast, lunch and dinner, but the animals you eat do. Cultivation of the staple crop takes up an area five times the size of the UK, and 85% of that area is used for animal feed. Thanks to projected rapid growth in both world population and in the meat-eating global middle class, demand for soybean is set to grow 80% by 2050 – more than any other staple crop.
