"Humanity is an urban species - more than half of us live in cities. Cities have proven to be the best incubators for innovation, the front lines in the war against climate change, and the stepping stones to the middle class. The Lincoln Institute of Land Policy estimates the urban population of Earth is set to double in the next 43 years, while urban land cover will double in just 19 years. But people won't just flock to the cities we have now - there are hundreds, and potentially thousands of cities waiting to be born."
Lindsay writes that governments, corporations and individuals are working to design the cities of the future, and wonders what they will have to do to make cities that work.
