As of 2015, one in three people worked in agriculture globally. With agriculture contributing only 3 percent of the global GDP, it is challenging for those workers to earn a living wage. Concerns are levied against companies in the food industry, with questions raised about their ethics and their treatment of workers, livestock, and the environment. The massive scale of the industry makes regulation difficult, but under-regulation can result in public health crises. The diverse viewpoints in this volume explore the controversies, challenges, and solutions involved in providing food in our world today.
