When the first groups of early humans stood up and foraged on the plains of East Africa, they solved their food shortages by walking somewhere new. In other words, Dr. M. Sanjayan said, “Humans were never sustainable in one place.”
Sanjayan, a scientist and member of Conservation International’s senior leadership team—whom you may have seen on nature shows like Big Blue Live and Earth: A New Wild—proposed this concept in a keynote address that kicked off the Aquarium’s 11th annual Sustainable Foods Institute in Monterey.
Within a few days’ walk, Sanjayan said, our early ancestors were able to find new, unexploited resources, which they would deplete over time, then migrate again.
Today, our planet has 7 billion human mouths to feed. And nearly every inch of inhabitable land is already spoken for. “To achieve sustainability, we have to innovate,” Sanjayan said. “And we only have a couple of generations to pull it off.”
