Each year, the global population grows by about 75 million. By 2020, almost 800 million people — more than twice the number in North America today — are expected to be added to the current world population. It is a simple reality that more people mean more food must be produced.
While population has grown at a steady pace, its composition is changing. Most growth is occurring in developing countries and, more specifically, in urban areas. Urban dwellers today account for around half of the world population, but this share is expected to rise to more than two-thirds by 2050. This is an important shift as urban consumers tend to eat higher-quality diets that include meat, fruits and vegetables.
