"By the middle of the century, one in three people on the planet will be living in inadequate, often illegal housing," says Cameron Sinclair, co-founder of Architecture for Humanity. "I mean, think about that! The formal architectural profession does not have anything like the capacity to meet people's needs on that scale. Worse, many of the people working in this space are unaware of each other's work. There's a vast replication of effort, not only the same successes, but the same failures. We need millions of solutions, and we need to share them all across the world."
