“We could have a tipping point in global food and agriculture if surging demand surpasses the agricultural system’s structural capacity to produce food,” says Sara Menker.

When Menker left her career in commodities trading to go figure out how the global value chain of agriculture works, she discovered that the world might be running out of food, and fast! She says governments may fall and we’ll probably starve within a decade. “The world could be short 214 trillion calories per year by 2027.” In this TED Talk video, she provides her vision of the future the world might face as well as a few steps on what we can do about it.
