Food production has increasingly become a huge business for a handful of giant corporations. Soyalism follows the industrial production chain of pork and the related soybean monoculture, from China to Brazil through the United States and Mozambique. The documentary describes the enormous concentration of power in the hands of these Western and Chinese companies. Meanwhile hundreds of thousands of small producers have gone out of business, and entire landscapes have been permanently transformed. The system has been exported across the world. From waste-lagoons in North Carolina to soybean monoculture in the Amazon rainforest, the movie asks whether this process is jeopardizing the environmental balance of the planet.
