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.
Just as humans have always sought food to survive, we have also sought the means to preserve that food. Right from the very moment of a kill or a harvest, food begins to break down. With preservation, we can plan for times of scarcity during times of plenty.
Industrialization brought the second great food revolution. Over the brief span of the 20th century, agriculture underwent greater change than it had since it was first practiced some 12,000 years ago.
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.
