Less than a decade ago, our planet reached a key inflection point: For the first time in human history, the majority of the population resided in cities. In fact, over 50 percent of the world's population has now settled on less than two percent of the Earth's surface area.
Rapid urban migration and an explosive growth in megacities are two international phenomena that are putting present-day metropolitan areas under enormous strain. Factor in global warming, resource scarcity, and a bourgeoning middle class, and it's clear that we need smart solutions to carry our cities forward into the future.
