With the global population expanding beyond 7 billion people,1 economists, statisticians, demographists, philosophers, and politicians have tried to resolve questions about whether or not there will be enough resources for a growing populace, and how to provide the required food, water, or land necessary to support human survival. Industry leaders have also grappled with these types of questions, albeit on a lesser scale, as to whether there will be sufficient access to raw materials needed to sustain economic growth.
