A global food crisis may be only a decade away | Sara Menker

Sara Menker quit a career in commodities trading to figure out how the global value chain of agriculture works. Her discoveries have led to some startling predictions: "We could have a tipping point in global food and agriculture if surging demand surpasses the agricultural system's structural capacity to produce food," she says. "People could starve and governments may fall." Menker's models predict that this scenario could happen in a decade -- that the world could be short 214 trillion calories per year by 2027. She offers a vision of this impossible world as well as some steps we can take today to avoid it.

Science in service to the public good | Siddhartha Roy

Science in service to the public good | Siddhartha Roy

We give scientists and engineers great technical training, but we're not as good at teaching ethical decision-making or building character. Take, for example, the environmental crisis that recently unfolded in Flint, Michigan -- and the professionals there who did nothing to fix it. Siddhartha Roy helped prove that Flint's water was contaminated, and he tells a story of science in service to the public good, calling on the next generation of scientists and engineers to dedicate their work to protecting people and the planet.
