Humans have depended on fire for millennia, but do we fully understand the impact it has had on our diet? When our hunter-gatherer ancestors learned to harness this tool, it ignited a culinary and cerebral revolution believed to be one of the most important factors in our evolution.

From the first row of planted crops, the practice of agriculture rendered man's hunter-gatherer lifestyles obsolete in favor of settled life and stable food supplies. This led to a skyrocketing population and enabled humans to develop skills outside of gathering the food needed to survive.

Industrialized and processed food has dominated the last century. Now, the question is, what's next? We go around the world to meet pioneers in urban farming, veganism, and insect protein production to find out what will be the future of food.
