It has been known for some time that food production is yet another looming catastrophe for the world. Climate change, plus the wasteful practices of the western world (the US throws away or never harvests almost half of its food, and the rest of the world is not much better) is a major part of the problem.
But it turns out the biggest problem may be prosperity -- with more countries successfully raising their living standards, the tendency is to migrate toward more animal-origin food sources. This article talks about research in one particular area -- substitutes for chicken eggs.
In its typically informative and fact-based manner, PBS has formed a joint effort with Public Radio International's Center for Investigative Reporting to study what else is being done about the problem.
